Q: The toothpaste in Anne's family's bathroom contains 105 grams. Anne's dad uses 3 grams at each brushing, her mom uses 2 grams, Anne and her brother use 1 gram each. Each member of the family brushes their teeth three times a day. How many days will it take for the toothpaste to run out?
A: Anne and her brother use 1 gram + 1 gram = 2 grams. Anne's dad uses 3 grams and Anne's mom uses 2 grams so together they use 2 grams + 3 grams + 2 grams = 7 grams / wash. Each day, the family uses 7 grams / wash * 3 washes / day = 21 grams. Using that amount daily, the toothpaste will last 105 grams / 21 grams / day = 5 days. The answer is 5.
Question: Merry had 50 boxes of apples on Saturday and 25 boxes on Sunday. There were 10 apples in each box. If she sold a total of 720 apples on Saturday and Sunday, how many boxes of apples are left?
Answer: Merry had a total of 50 + 25 = 75 boxes of apples. These 75 boxes is equal to 75 x 10 = 750 apples. There were 750 - 720 = 30 apples left. Thus, 30 / 10 = 3 boxes of apples are left. The answer is 3.
[Question]A boat is traveling across a square lake at 10 MPH. It takes 2 hours to go across the length of the lake. It then travels the whole width of the lake at the same speed, which takes 30 minutes. How many square miles is the lake?
[Answer]The lake is 20 miles across because 2 x 10 = 20. If takes .5 hours to go from bottom to top because 30 / 60 = .5. The lake is five miles from bottom to top because 10 x .5 = 5. The square mileage is 100 because 20 x 5 = 100. The answer is 100.
Q: Tomorrow, Pete must finish paying off the last $90 he owes on a bike. He goes through his wallet and finds two $20 bills. Checking his pockets, he finds four $10 bills. Unhappy that he doesn't have the entire amount, he suddenly remembers that he has plastic bottles that can be returned to his local store for cash. If the store pays 50 cents for each bottle, how many bottles will Pete have to return to the store?
A: Pete’s wallet contains 2 * 20 = 40 dollars. The money in Pete’s pockets is 4 * 10 = 40 dollars. In total Pete has 40 + 40 = 80 dollars. He owes 90 dollars on the bike and therefore needs 90 - 80 = 10 more dollars. Since 50 cents is ½ dollar, then the number of bottles required to get 10 dollars is 10 / (1 / 2) = 10 * 2 = 20 bottles. The answer is 20.
