Ian bought a washing machine and a home theater system. The original price of the washing machine was $3600 and the original price of the home theater system was half the original price of the washing machine. Ian was given a 24% discount on the home theater system. How much did Ian pay altogether?
Original price of the home theater system
= 3600 ÷ 2
= $1800

Discounted price of the home theater system in percent
= 100% - 24%
= 76%

100% of the price of the home theater system = 1800
1% of the price of the home theater system = 1800 ÷ 100 = 18
76% of the price of the home theater system = 76 x 18 = 1368

Discounted price of the home theater system = $1368

Total amount that Ian paid
= 3600 + 1368
= $4968

Answer(s): $4968
