Albert bought a computer and a home theater system. The original price of the computer was $3000 and the original price of the home theater system was half the original price of the computer. Albert was given a 30% discount on the home theater system. How much did Albert pay altogether?
Original price of the home theater system
= 3000 ÷ 2
= $1500

Discounted price of the home theater system in percent
= 100% - 30%
= 70%

100% of the price of the home theater system = 1500
1% of the price of the home theater system = 1500 ÷ 100 = 15
70% of the price of the home theater system = 70 x 15 = 1050

Discounted price of the home theater system = $1050

Total amount that Albert paid
= 3000 + 1050
= $4050

Answer(s): $4050
