Answer:

The original cost of dinner was $14.20

Step-by-step explanation:

Because we used a 25% coupon, we know that we paid 75% of the meal cost. First we must subtract what we paid for tip.

$13.65 - $3.00 = $10.65

Since $10.65 was 75% of the cost, we can divide the cost by the percentage (make sure to turn it into a decimal first).

$10.65/.75 = $14.20
