Warren bought a washing machine and a refrigerator. The original price of the washing machine was $3600 and the original price of the refrigerator was half the original price of the washing machine. Warren was given a 18% discount on the refrigerator. How much did Warren pay altogether?
Original price of the refrigerator
= 3600 ÷ 2
= $1800

Discounted price of the refrigerator in percent
= 100% - 18%
= 82%

100% of the price of the refrigerator = 1800
1% of the price of the refrigerator = 1800 ÷ 100 = 18
82% of the price of the refrigerator = 82 x 18 = 1476

Discounted price of the refrigerator = $1476

Total amount that Warren paid
= 3600 + 1476
= $5076

Answer(s): $5076
