John buys 8 packs of cookies at the grocery store. The cookies ar eon sale for 50 cents off per pack. He speands 20.00. Which equation can be used to find the original cost of cookies?

Answer 1

Let x be the original cost of cookies.
The discounted cost of each pack of cookies is x - 0.50.
So, the total cost of 8 packs of cookies is 8(x - 0.50).
We know that John spent $20.00, so 8(x - 0.50) = 20.
This equation can be used to find the original cost of cookies. Answer: \boxed{8(x-0.50) = 20}.
