Answer: Emily's price is 33.6
Step-by-step explanation:
The original price of the backpack(just Don't Rock)that she likes of is 60 but everything on the Rock comes with the 30% off discount. It means that the amount taken off is
30/100 × 60 = 18
The price for which it was available is
60 - 18 = 42
Emily has a coupon for 20% off your purchase at the store. It means that the amount that would be taken off the backpack that she wants to buy is
20/100 × 42 = 8.4
The final price that she would pay is
42 - 8.4 = 33.6
