What is the final price that linh pays?

$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
