Question

Responses

8(c+0.50)=20

8c−0.50=20

8(c−0.50)=20

8−0.50c=20

Answer 1

To determine the original cost of a box of cookies \( c \) given that John buys 8 packs of cookies at a discounted price, we can set up the equation based on the information provided.

Since each pack has a discount of 50 cents, the price he pays for each pack is \( c - 0.50 \). Therefore, the total cost for 8 packs can be expressed as:

\[ 8(c - 0.50) = 20 \]

This matches the option:

8(c−0.50)=20

So the correct equation to use is:

8(c - 0.50) = 20
