Answer:

$899.15

0.85(1199) - 120

Step-by-step explanation:

To find the purchase total, multiply the price by the percent paid and subtract the certificate.

The store offers a 15% discount. This means you pay 85% of the price. So the discounted price is 0.85(1199) = 1019.15

Subtract the certificate 1019.15 - 120 = 899.15

The composite function is 0.85(1199) - 120.
