Answer: $835.88
Step-by-step explanation:
SP after 7% sales tax = 543.32
SP = MP (100 - d) / 100
543.32 = MP (100 - 35) / 100
543.32 = 0.65MP
MP = 835.88
W + L = 96
w = 2L
2L + L = 96
3L = 96
L = 96/3
L = 32.....so they lost 32
w = 2L
w = 2(32)
w = 64 <== they won 64 games
You have to add
So the coupon subtracts 17.95 from X price and you pay $71.80 for the headphones
17.95 + 71.80 = $89.75 (Original Price)
