Question

The function b(x) = 2x − 5 determines how many bags of dog food need to be purchased for an animal shelter, where x is the number of dogs at the shelter. The shelter manager uses m(b(x)) to find the amount of money to bring for the dog food purchase. The function m(x) = 3x + 1. Solve for how much money to bring when there are 10 dogs in the shelter.

Answer 1

15
31
46
52

Answer 2

Plug 10 into the equation and you get 15. Use 15 to plug in next
m(x) = 3x + 1
put x = 15
m(15) = 3(15) + 1
= ?
