Greg drives 30 miles from his workplace to the farmer's market. After buying his groceries at the farmers market, he drives home. To get home, he travels for 30 minutes at 20 miles per hour. How many miles in total does Greg travel?

We must first convert minutes to hours, so 30 minutes * (1 hour/60 minutes) =

<<30*(1/60)=0.5>>0.5 hours The number of miles Greg travels on his trip home is 0.5 hours * 20 mph = <<0.5*20=10>>10 miles The total miles Greg travels is 10 + 30 = <<10+30=40>>40 miles #### 40 Jemma saw 7 grasshoppers on her African daisy plant. Then, hopping on the grass under the plant, she found 2 dozen baby grasshoppers. How many grasshoppers did Jemma find altogether? Jemma found 2 x 12 = <<2*12=24>>24 baby grasshoppers. In total, she found 24 + 7 = <<24+7=31>>31 grasshoppers. #### 31 Teairra has 5 shirts and 24 pairs of pants in her closet. If 3 of Teairra's shirts are plaid and 5 of Teairra's pants are purple, how many shirts and pants does Teairra has which are neither plaid nor purple? If 3 of Teairra's shirts are plaid, 5-3=2 shirts are not plaid. Also, 5 of Teairra's pants are purple, meaning 24-5=<<24-5=19>>19 pants are not purple The number of shirts and pants that Teairra has which are neither plaid nor purple is 19+2=<<19+2=21>>21 #### 21 Bobby buys two packets of candy. He eats two candies every day from Monday through Friday and takes one each during the remaining days of the week. If it takes him 3 such weeks to finish the 2 packets, how many candies are in a packet? He eats 2 each from Monday through Friday for a total of 2*5 = <<2*5=10>>10 candies He eats 1 each every other day of the week (Saturday and Sunday) for a total of 1*2 = <<1*2=2>>2 candies In a week, he consumes a total of 10+2 = <<10+2=12>>12 candies Doing this for 3 weeks, he will consume 3*12 = <<3*12=36>>36 candies If 2 packets contain 36 candies, then 1 contains 36/2 = 18 candies #### 18 Two companies A and B, are selling bottled milk. Company A sells a big bottle for $4 and Company B sells a big bottle for $3.5. Company A was able to sell 300 and company B 350 big bottles of milk. How much more money did one company make from the other? Company A earned 300 * 4 = $<<300*4=1200>>1200 for big bottles of milk. Company B earned 350 * 3.5 = $<<350*3.5=1225>>1225 for big bottles of milk. Company B earned 1225 - 1200 = $<<1225-1200=25>>25 more than company A. #### 25 Three times the sum of marbles that Atticus, Jensen, and Cruz have is equal to 60. If Atticus has half as many marbles as Jensen, and Atticus has 4 marbles, how many marbles does Cruz have? Three times the sum of marbles that Atticus, Jensen, and Cruz have is equal to 60, meaning together they have 60/3=<<60/3=20>>20 marbles. If Atticus has half as many marbles as Jensen, and Atticus has four marbles, Jensen has 2*4=<<4*2=8>>8 marbles. Together, Atticus and Jensen have 8+4=<<8+4=12>>12 marbles. Since the sum of marbles that Atticus, Jensen, and Cruz have is equal to 20, and Atticus and Jensen have 12 marbles, Cruz has 20-12=<<20-12=8>>8 marbles. #### 8 Today Geoff bought 2 pairs of sneakers and spent $60 equally between the two. Tomorrow, he's going to spend 4 times as much on sneakers than he did on Monday. Wednesday, he'll spend 5 times as much on sneakers than he did on Monday. How much will Geoff spend on sneakers over these three days? Tomorrow Geoff will spend 60*4 = <<60*4=240>>240 dollars. Wednesday Geoff will spend 60*5 = <<60*5=300>>300 dollars. Total spent in three days is 60+240+300 = <<60+240+300=600>>600 dollars. #### 600 Jackson works 5 days a week going door-to-door collecting for charity. His goal is to raise $1000 for the week. He earned $300 on Monday and $40 on Tuesday. If he collects an average of $10 for every 4 houses he visits, how many houses will he have to visit on each of the remaining days of the week to meet his goal? First find the total amount Jackson still needs to collect: $1000 - $300 - $40 = $<<1000-300-40=660>>660 Then subtract the number of days he already worked from the number of workdays in the week to find how many more days he'll work: 5 days - 2 days = <<5-2=3>>3 days Then divide the total amount he still needs to earn by the number of days he has to earn it to find how much he needs to earn per day: $660 / 3 days = $<<660/3=220>>220/day Then find how much money he collects per house: $10 / 4 houses = $<<10/4=2.50>>2.50/house Then divide the amount he needs to collect per day by the amount he collects per house to find how many houses he needs to visit per day: $220/day / $2.50/house = <<220/2.5=88>>88 houses/day #### 88 Bob has planted corn in his garden, and it has just started to sprout. A week after planting it, it had grown 2 inches. The next week, its height increased by twice as much as it had the first week. In the third week, it grew 4 times as much as it did the week before. How tall are the corn plants now? The second week it grew twice as much as the first week, so 2 * 2 inches = <<2*2=4>>4 inches. The third week it grew 4 times as much as in the second week, so 4 * 4 inches = <<4*4=16>>16 inches. In total, it grew 2 inches + 4 inches + 16 inches = <<2+4+16=22>>22 inches. #### 22 Cheyenne is a craftswoman making pots for sale. On a particular week, she made 80 clay pots. However, when she put them in the sun to dry, 2/5 of the pots cracked and could not be sold. How much money did Cheyenne make from selling the remaining items at $40 per clay pot? When she put them in the sun to dry, 2/5*80 = <<2/5*80=32>>32 of the clay pots that Cheyenne made cracked and could not be sold. The number of pots that were good for sale is 80-32 = <<80-32=48>>48 If she sold each clay pot at $40, she earned $40*48 = $<<40*48=1920>>1920 from selling the good pots. #### 1920
