Xavier bought a computer and a portable air-conditioner. The original price of the computer was $2000 and the original price of the portable air-conditioner was half the original price of the computer. Xavier was given a 16% discount on the portable air-conditioner. How much did Xavier pay altogether?
Original price of the portable air-conditioner
= 2000 ÷ 2
= $1000

Discounted price of the portable air-conditioner in percent
= 100% - 16%
= 84%

100% of the price of the portable air-conditioner = 1000
1% of the price of the portable air-conditioner = 1000 ÷ 100 = 10
84% of the price of the portable air-conditioner = 84 x 10 = 840

Discounted price of the portable air-conditioner = $840

Total amount that Xavier paid
= 2000 + 840
= $2840

Answer(s): $2840
