Tim has 30 less apples than Martha, and Harry has half as many apples as Tim. If Martha has 68 apples, how many apples does Harry have?
Tim has 68-30 =
<<68-30=38>>38 apples. Harry has 38/2 = <<38/2=19>>19 apples. #### 19 At a flea market, Hillary sells handmade crafts for 12 dollars per craft. Today, Hillary sells 3 crafts and is given an extra 7 dollars from an appreciative customer. Later on, Hillary deposits 18 dollars from today's profits into her bank account. How many dollars is Hillary left with after making the deposit? Hillary sells 3 crafts for 12 dollars each, for a total of 3 crafts * $12/craft = $<<3*12=36>>36 She receives an extra 7 dollars from a customer, increasing the total to $36 + $7 = $<<36+7=43>>43 She then deposits 18 dollars in the bank, leaving her with $43 - $18 = $25 #### 25 Nancy is filling an aquarium for her fish. She fills it halfway and goes to answer the door. While she's gone, her cat knocks the aquarium over and spills half the water in it. Then Nancy comes back and triples the amount of water in the aquarium. If the aquarium is 4 feet long, 6 feet wide, and 3 feet high, how many cubic feet of water are in the aquarium? First calculate the volume of the aquarium by multiplying its length, width and height: 4 ft * 6 ft * 3 ft = <<4*6*3=72>>72 cubic ft Then figure out what proportion of the aquarium is full after the cat knocks it over: 1/2 * 1/2 = 1/4 Then figure out what proportion of the aquarium is full after Nancy refills it: 3 * 1/4 = 3/4 Now multiply the proportion of the aquarium that's full by the aquarium's volume to find out how much water is in it: 72 cubic ft * 3/4 = <<72*3/4=54>>54 cubic ft #### 54 It is Roger’s turn to provide a snack for the baseball team after the game and he has decided to bring trail mix. The trail mix comes in packs of 6 individual pouches. Roger has 13 members on his baseball team, plus 3 coaches and 2 helpers. How many packs of trail mix does he need to buy? Roger will need 13 + 3 + 2 = <<13+3+2=18>>18 pouches of trail mix. If you divide the amount of trail mix pouches by the amount in each pack, 18 / 6 = <<18/6=3>>3 packs of trail mix. #### 3 Four people lost a total of 103 kilograms of weight. The first person lost 27 kilograms. The second person lost 7 kilograms less than the first person. The two remaining people lost the same amount. How many kilograms did each of the last two people lose? Second person = 27 - 7 = <<27-7=20>>20 kg 103 - 27 - 20 = <<103-27-20=56>>56 kg 56/2 = <<56/2=28>>28 kg The last two people each lost 28 kilograms of weight. #### 28 Dale and Andrew had breakfast at a cafe. A slice of toast costs £1, and eggs cost £3 each. Dale had 2 slices of toast and 2 eggs. Andrew had 1 slice of toast and 2 eggs. How much did their breakfast cost? The cost of Dale's toast is 2 × $1 = $<<2*1=2>>2. The cost of Andrew's toast is 1 × $1 = $<<1*1=1>>1. The cost of Dale's eggs is 2 × $3 = $<<2*3=6>>6. The cost of Andrew's eggs is 2 × $3 = $<<2*3=6>>6. Their breakfast cost $2 + $1 + $6 + $6 = $<<2+1+6+6=15>>15. #### 15 A garden produced 237 potatoes, 60 fewer cucumbers and twice as many peppers than the cucumbers. How many vegetables did the garden produce? The garden produced 237 potatoes - 60 = <<237-60=177>>177 cucumbers. The garden produced 177 cucumbers * 2 peppers/cucumber = <<177*2=354>>354 peppers. The garden produced 237 potatoes + 177 cucumbers + 354 peppers = <<237+177+354=768>>768 vegetables. #### 768 A boxer weighs 97 kg at 4 months from a fight. He is on a diet that allows him to lose 3 kg per month until the day of the fight. How much will he weigh on the day of the fight? In 4 months, he will lose 3 x 4 = <<3*4=12>>12 kilograms. So his weight will be 97 – 12 = <<97-12=85>>85 kilograms. #### 85 Manny had 3 birthday cookie pies to share with his 24 classmates and his teacher, Mr. Keith. If each of the cookie pies were cut into 10 slices and Manny, his classmates, and Mr. Keith all had 1 piece, how many slices are left? There is a total of 3 x 10 = <<3*10=30>>30 cookie slices. There are 24 + 1 + 1 = <<24+1+1=26>>26 people who ate the cookie pieces. There is 30 - 26 = <<30-26=4>>4 cookie slices left. #### 4 James spends 40 years teaching. His partner has been teaching for 10 years less. How long is their combined experience? His partner has been teaching for 40-10=<<40-10=30>>30 years So together they have 40+30=<<40+30=70>>70 years of experience #### 70
