A soccer ball takes twenty minutes to inflate. Alexia and Ermias are inflating balls, with Alexia inflating 20 balls and Ermias inflating 5 more balls than Alexia. Calculate the total time in minutes they took to inflate all the soccer balls.
Let's think: To inflate a soccer ball, it takes 20 minutes, and if Alexia inflated 20 soccer balls, she took 20 * 20 = 400 minutes. Ermias has 5 more soccer balls than Alexia, meaning she has a total of 20 + 5 = 25 soccer balls. If each soccer ball takes 20 minutes to inflate, Ermias took 25 * 20 = 500 minutes to inflate all the soccer balls she had. Alexia and Ermias took 400 + 500 = 900 minutes to inflate all the soccer balls.. The answer is: 900.

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?
Let's think: 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.. The answer is: 840.

Mark collects money for the homeless. He visits 20 households a day for 5 days and half of those households give him a pair of 20s. How much did he collect?
Let's think: He got money from 20 / 2 = 10 households per day. So that means he got money from 10 * 5 = 50 households. Each of those houses gave 20 * 2 = $40. So he raised 40 * 50 = $2000.. The answer is: 2000.

Stacy has 2 more than triple as many berries as Steve. Steve has one half as many berries as Skylar. If Skylar has 20 berries, how many berries does Stacy have?
Let's think:
Steve has (1 / 2)(20) = 10 berries. Stacy has 2 + 3(10) = 32 berries.. The answer is: 32.
