Ken bought a refrigerator and a home theater system. The original price of the refrigerator was $3200 and the original price of the home theater system was half the original price of the refrigerator. Ken was given a 36% discount on the home theater system. How much did Ken pay altogether?
Original price of the home theater system
= 3200 ÷ 2
= $1600

Discounted price of the home theater system in percent
= 100% - 36%
= 64%

100% of the price of the home theater system = 1600
1% of the price of the home theater system = 1600 ÷ 100 = 16
64% of the price of the home theater system = 64 x 16 = 1024

Discounted price of the home theater system = $1024

Total amount that Ken paid
= 3200 + 1024
= $4224

Answer(s): $4224
