Answer:
$12
Step-by-step explanation:
Hi there!
What we know:
- Brooklyn bought 8 bags of dog food
- Brooklyn also used a $5 coupon
- The total was $91
Therefore, 8 × (cost of 1 bag) - 5 = 91
Form an equation with x as the cost of 1 bag of dog food:
8 × (cost of 1 bag) - 5 = 91

Add 5 to both sides

Divide both sides by 8

Therefore, 1 bag of dog food costs $12.
I hope this helps!
