7. An item bought for $400 is sold for $340. Calculate the percentage loss.
15%
Loss = $400 − $340 = $60. Percentage loss = ($60 ÷ $400) × 100% = 15%.
8. An item bought for $360 is sold for $288. Calculate the percentage loss.
20%
Loss = $360 − $288 = $72. Percentage loss = ($72 ÷ $360) × 100% = 20%.
