Answer:
$67.90
Step-by-step explanation:
First lets calculate the subtotal, or the price before the coupon is added:
2(12)+1(28)+1(45)=97
Subtotal: $97.00
Okay Now lets apply the coupon, to do this we'll multiply the subtotal by 0.7 since the coupon removes 30% from the price and 1 - 0.3 = 0.7
97 * 0.7 = 67.9
Total: $67.90
