Answer:
2
Step-by-step explanation:
if x=4
4/5 (2(4)+7) - 2/3(2(4)+7)
4/5 (8+7) - 2/3(8+7)
4/5(15) -2/3(15)
12 - 10

Part a: 21 dollars because you multiply .40 with 5 and get 6. you add the 6 to the 15 and get 21.
part b: 30.21 because you multiply 38 by .25 and get the answer for that and then subtract that number from 38. then you multiply 0.06 by 38 and when u get that number, add that to the discounted price.
