Question

Sonny is shopping on the internet. He is going to buy 10 dog toys for his brother, Hank, as a gift and some additional dog toys for himself. Each dog toy costs $2.35, and Sonny can spend up to $30 in all. Which inequality can be solved for n, the number of additional dog toys Sonny can buy for himself?

Answer 1

The inequality that can be solved for n is:

$2.35(10) + $2.35n ≤ $30

23.50 + 2.35n ≤ 30

2.35n ≤ 6.50

n ≤ 6.50 / 2.35

n ≤ 2.77

Therefore, Sonny can buy up to 2 additional dog toys for himself.
