Guy has saved a total of $95. He buys an airplane model kit for $9, and he wants to donate $8 to each of several local animal shelters. How much money will he have left if he donates to as many animal shelters as possible?

Answer: he would have $6 left.

Step-by-step explanation:

Let x represent the number of local animal shelters that he donates.

He buys an airplane model kit for $9 and he wants to donate $8 to each of several local animal shelters. This means that the total amount that he would spend if he bought x local animal shelters is

9 + 8x

Guy has saved a total of $95. This means that

9 + 8x = 95

8x = 95 - 9

8x = 86

x = 10.75

The number of local animal shelters that he can buy is 10.

The amount that he will have left if he donates to as 10 local animal shelters is

95 - (80 - 9) = $6

Step-by-step explanation:

Step 1. 95-8=86 (bought 1 plane kit)

Step 2. Find how many planes he can buy with the remainder of the money

86/8=10.75

Therefore he can only buy 10 planes to donate to the animal shelter as he will won't have enough money to by 11 planes.
