Question: It takes 2.5 hours to groom a dog and 0.5 hours to groom a cat. What is the number of minutes it takes to groom 5 dogs and 3 cats?
Answer with step-by-step thinking: 2.5 * 5 = 12.5 hours. 0.5 * 3 = 1.5 hours. 12.5 + 1.5 hours = 14 hours. 14 hours = 14 * 60 = 840 minutes. It would take 840 minutes to groom 5 dogs and 3 cats.
So the answer is 840.


Question: John hits 70% of his free throws. For every foul he gets 2 shots. He gets fouled 5 times a game. How many free throws does he get if he plays in 80% of the 20 games the team plays?
Answer with step-by-step thinking: John plays in 20 * .8 = 16 games. That means he gets fouled 16 * 5 = 80 fouls. So he gets 80 * 2 = 160 foul shots. So he makes 160 * .7 = 112 free throws.
So the answer is 112.


Question: Jenna is adding black dots to a bunch of white blouses. Each blouse gets 20 dots, and each dot takes 10 ml of black dye. How many 400-ml bottles of dye does Jenna need to buy to dye 100 blouses?
Answer with step-by-step thinking:
First find the amount of dye each blouse takes: 20 dots / blouse * 10 ml / dot = 200 ml / blouse. Then multiply the dye used per blouse by the number of blouses to find the total amount of dye used: 200 ml / blouse * 100 blouses = 20000 ml. Then divide the amount of dye needed by the amount of dye per bottle to find the number of bottles needed: 20000 ml / 400 ml / bottle = 50 bottles.
So the answer is 50.
