Question

HELP PLEASE!!!!!!!!!!!

Cassie has a coupon for 30% off the cost of dinner at a local restaurant. With the coupon, she saves $6 on her dinner. What was the original cost of her dinner? Explain how you know.

Answer 1

$20.

Explanation:

$6 is 30 % of the original cost.

30% = 0.30 as a decimal fraction.

If the original cost is x dollars then we have the equation:

0.30x = 6

x = 6 / 0.30

= $20.
