Question

An animal clinic charges $40 for vaccinations of kittens and $55 for vaccinations of puppies. Last week, the clinic earned $1,450 from vaccinations, including 14 puppies. How many kittens were vaccinated at the clinic last week?

Answer 1

If i am correct, 17 kittens

Answer 2

Set up your equation:

55(14puppies) + 40(kittens) = 1450

Solve:

770 + 40(x) = 1450

1450 - 770 = 40x
680 ÷ 40 = x

x = 17
