Howard bought a television and a home theater system. The original price of the television was $3600 and the original price of the home theater system was half the original price of the television. Howard was given a 20% discount on the home theater system. How much did Howard pay altogether?
Original price of the home theater system
= 3600 ÷ 2
= $1800

Discounted price of the home theater system in percent
= 100% - 20%
= 80%

100% of the price of the home theater system = 1800
1% of the price of the home theater system = 1800 ÷ 100 = 18
80% of the price of the home theater system = 80 x 18 = 1440

Discounted price of the home theater system = $1440

Total amount that Howard paid
= 3600 + 1440
= $5040

Answer(s): $5040
