A certain store is selling an $80 radio $64. If a different radio had a list price of $200 and was discounted at 1.5 times the percent discount on the $80 model, what would its selling price be?
a) $90
b) $105
c) $120
d) $140
e) $160

Cost = (64/80)*100% = 80% of full price.
Discount = 100%-80% = 20%.

Discount = 1.5*20% = 30%.
Cost = 200-0.3*200 = $140.
