Answer:

$15

Step-by-step explanation:

Let d represent the cost of the dinner before tip.  Then $15 = 0.20d, since 0.20 is the decimal fraction corresponding to 20%.

Solving for d, the cost of the dinner, we divide both sides of the equation $15 = 0.20d by .20, obtaining:

        $15

d = ------------ = $75

         0.20

The cost of the dinner before tip was $75.
