Ivan bought a notebook and a portable air-conditioner. The original price of the notebook was $3600 and the original price of the portable air-conditioner was half the original price of the notebook. Ivan was given a 17% discount on the portable air-conditioner. How much did Ivan pay altogether?
Original price of the portable air-conditioner
= 3600 ÷ 2
= $1800

Discounted price of the portable air-conditioner in percent
= 100% - 17%
= 83%

100% of the price of the portable air-conditioner = 1800
1% of the price of the portable air-conditioner = 1800 ÷ 100 = 18
83% of the price of the portable air-conditioner = 83 x 18 = 1494

Discounted price of the portable air-conditioner = $1494

Total amount that Ivan paid
= 3600 + 1494
= $5094

Answer(s): $5094
