There were 40 kids on Lake Pleasant. A fourth of the kids went tubing, but only half of the tubers went rafting. How many of the kids who joined the rafting excursion were also on the tubing excursion?

How many kids went tubing? ** 40/4 =

<<40/4=10>>10 kids went tubing. How many kids went rafting and tubing? ** 10/2 = <<10/2=5>>5 kids went rafting and tubing. #### 5 In her first term, Governor Sandoval gave twice as many commencement addresses as Governor Hawkins. Governor Sloan gave ten more commencement addresses than Governor Sandoval in the same amount of time. If Governor Sandoval gave 12 commencement addresses, how many commencement addresses did the three of them give altogether? How many commencement addresses did Governor Hawkins give? ** Since Governor Sandoval gave 12 commencement addresses, twice the number that Governor Hawkins gave, Governor Hawkins gave 12/2 = <<12/2=6>>6 commencement addresses. How many commencement addresses did the two of them give altogether? ** The two of them gave 6+12 = <<6+12=18>>18 commencement addresses in total. How many commencement addresses did Governor Sloan give? ** Governor Sloan gave ten more commencement addresses than Governor Sandoval, a total of 12+10 = <<12+10=22>>22 commencement addresses. How many commencement addresses did the three of them give altogether? ** The three of them gave 22+18 = <<22+18=40>>40 commencement addresses. #### 40 Bill put his french fries in the oven after it finished heating. The recommended time was 5 minutes for them to be fully cooked. He put them in for 45 seconds. How many seconds remained? How many seconds are in 5 minutes? ** Each minute last 60 seconds, so that means for the fries to be fully cooked Bill needs to cook them for 5*60=<<5*60=300>>300 seconds How many seconds are left? ** Since Bill had the fries in the oven for 45 seconds so far, that means they need to stay in the oven for another 300-45= <<300-45=255>>255 seconds. #### 255 Based on a 2008 study, children 6–11 years old spend 45 minutes each day watching television. How many hours do these children watch television in 2 weeks if they are allowed to watch television 4 days a week? How many minutes do the children watch in a week? ** The children watch a total of 45 x 4 = <<45*4=180>>180 minutes in a week. How many hours do the children watch in a week? ** In hours, this is equal to 180/60 = <<180/60=3>>3 hours a week. How many hours do these children watch in 2 weeks? ** Thus, these children watch 3 x 2 = <<3*2=6>>6 hours in two weeks. #### 6 Jimmy decides to make sandwiches for a picnic. He makes 8 sandwiches in total, using two slices of bread each. How many packs of bread does he need to buy to make these sandwiches, assuming he starts with no bread and each pack has 4 slices of bread in it? How many slices of bread will Jimmy use? ** First, we need to determine how many slices of bread Jimmy will use to make the sandwiches. We determine this by performing 8*2=<<8*2=16>>16 slices of bread needed. How many packs of bread does Jimmy need? ** We then divide the number of slices needed by the number of slices per bread pack, performing 16/4=<<16/4=4>>4 packs of bread needed. #### 4 Kylie picks apples for 3 hours. The first hour she picks 66 apples. The second hour she doubles her apple picking rate, and the third hour she picks a third of the apples picked in the first hour. How many apples did Kylie pick total? How many apples did Kylie pick in the first hour? ** First hour = 66 apples How many apples did Kylie pick in the second hour? ** Second hour = 66(2) = 132 apples How many apples did Kylie pick in the third hour? ** Third hour = 66(1/3) = 22 apples How many apples did Kylie pick in total? ** Total number of apples picked 66+132+22=<<66+132+22=220>>220 apples #### 220 Amoli and Anayet must travel 369 miles together. Amoli drove 42 miles an hour for 3 hours and Anayet drove at 61 miles an hour for 2 hours. How many miles do they still need to travel? How many miles did Amoli travel? ** Amoli = 42 * 3 = <<42*3=126>>126 miles How many miles did Anayet travel? ** Anayet = 61 * 2 = <<61*2=122>>122 How many miles did Amoli and Anayet travel together? ** Together = 126 + 122 = <<126+122=248>>248 miles How many miles do they still need to travel? ** 369 - 248 = <<369-248=121>>121 miles How many miles do they still need to travel? ** They still have 121 miles to travel. #### 121 A plumber is trying to decide which of three different jobs he should take to make the most money. The first job involves fixing three toilets and three sinks at an apartment complex. The second involves two toilets and five sinks at a different apartment complex. The third involves fixing one toilet, two showers and three sinks at a third apartment complex. If the plumber charges $30 to fix a sink, $40 to fix a shower and $50 to fix a toilet, what is the most money the plumber can earn if he can only choose one of these three jobs? How much money would the plumber earn if he chose the first job? ** If the plumber chooses the first job, he would earn 3*50 + 3*30 = $<<3*50+3*30=240>>240. How much money would the plumber earn if he chose the second job? ** If he chooses the second, he'd earn 2*50 + 5*30 = $<<2*50+5*30=250>>250. How much money would the plumber earn if he chose the third job? ** If he chooses the third, he'd earn 50 + 2*40 + 3*30 = $<<50+2*40+3*30=220>>220. How much money can the plumber earn from one of these jobs? ** Therefore, the most money he can earn from one of these jobs is $<<250=250>>250. #### 250 Three buckets are holding different fruits. Bucket A has 4 more pieces of fruit than bucket B while bucket B has 3 more pieces of fruit than bucket C. If bucket C has 9 pieces of fruit, how many pieces of fruit are in all 3 buckets? How many fruits are in bucket B? ** Bucket B has 3 more fruits than C (which has 9 fruits) for a total of 9+3 = <<3+9=12>>12 fruits How many fruits are in bucket A? ** Bucket A has 4 more fruits than B (which has 12 fruits) for a total of 12+4 = <<4+12=16>>16 fruits How many pieces of fruit are in all 3 buckets? ** All three buckets have a total of 9+12+16 = <<9+12+16=37>>37 fruits #### 37 Amber worked for 12 hours last weekend. Armand worked one-third as long and Ella worked twice as long. How many hours did the 3 people work in total? How long did Armand work? ** Armand = (1/3) * 12 = <<(1/3)*12=4>>4 hours How long did Ella work? ** Ella = 2 * 12 = <<2*12=24>>24 hours How long did Amber, Armand and Ella work? ** Total hours = 12 + 4 + 24 = <<12+4+24=40>>40 hours How many hours did the 3 people work in total? ** They worked a total of 40 hours. #### 40
