Explanation:
Brett bought three pairs of jeans and five polo shirts. The jeans that regularly sell for $79 were 35% off and the polo shirts that regularly sell for $39 were 15% off. If sales tax is 5.75% and he gave the cashier $350, how much did he receive back in change?
3 pairs jeans at regular price costs: 79 * 3 = 237
35% off so paying 65% of full price:
237 * 0.65 = discounted price of 154.05
5 polo shirts at regular price costs: 39 * 5 = 195
15% off so paying 85% of full price:
195 * 0.85 = discounted price of 165.75
cost of jeans and polo shirts at discounted prices: 154.05 + 165.75 = 319.8
Pay an additional 5.75% sales tax. So Brett is paying 1.0575 of the cost:
1.0575 * 319.8 = 338.1885. Rounded, it cost Brett $338.19 for his jeans and polo shirts.
Brett gave $350:
350 - 338.19 = $11.81 change received
