Tommy bought a dishwasher and a portable air-conditioner. The original price of the dishwasher was $3200 and the original price of the portable air-conditioner was half the original price of the dishwasher. Tommy was given a 39% discount on the portable air-conditioner. How much did Tommy pay altogether?
Original price of the portable air-conditioner
= 3200 ÷ 2
= $1600

Discounted price of the portable air-conditioner in percent
= 100% - 39%
= 61%

100% of the price of the portable air-conditioner = 1600
1% of the price of the portable air-conditioner = 1600 ÷ 100 = 16
61% of the price of the portable air-conditioner = 61 x 16 = 976

Discounted price of the portable air-conditioner = $976

Total amount that Tommy paid
= 3200 + 976
= $4176

Answer(s): $4176
