Henry bought a laptop and a portable air-conditioner. The original price of the laptop was $3800 and the original price of the portable air-conditioner was half the original price of the laptop. Henry was given a 12% discount on the portable air-conditioner. How much did Henry pay altogether?
Original price of the portable air-conditioner
= 3800 ÷ 2
= $1900

Discounted price of the portable air-conditioner in percent
= 100% - 12%
= 88%

100% of the price of the portable air-conditioner = 1900
1% of the price of the portable air-conditioner = 1900 ÷ 100 = 19
88% of the price of the portable air-conditioner = 88 x 19 = 1672

Discounted price of the portable air-conditioner = $1672

Total amount that Henry paid
= 3800 + 1672
= $5472

Answer(s): $5472
