2. An item bought for $380 is sold for $285. Calculate the percentage loss.
25%
Loss = $380 − $285 = $95. Percentage loss = ($95 ÷ $380) × 100% = 25%.
3. An item bought for $260 is sold for $143. Calculate the percentage loss.
45%
Loss = $260 − $143 = $117. Percentage loss = ($117 ÷ $260) × 100% = 45%.
4. An item bought for $80 is sold for $48. Calculate the percentage loss.
40%
Loss = $80 − $48 = $32. Percentage loss = ($32 ÷ $80) × 100% = 40%.
5. An item bought for $440 is sold for $220. Calculate the percentage loss.
50%
Loss = $440 − $220 = $220. Percentage loss = ($220 ÷ $440) × 100% = 50%.
6. An item bought for $300 is sold for $255. Calculate the percentage loss.
15%
Loss = $300 − $255 = $45. Percentage loss = ($45 ÷ $300) × 100% = 15%.
7. An item bought for $440 is sold for $418. Calculate the percentage loss.
5%
Loss = $440 − $418 = $22. Percentage loss = ($22 ÷ $440) × 100% = 5%.
8. An item bought for $340 is sold for $204. Calculate the percentage loss.
40%
Loss = $340 − $204 = $136. Percentage loss = ($136 ÷ $340) × 100% = 40%.
9. An item bought for $140 is sold for $112. Calculate the percentage loss.
20%
Loss = $140 − $112 = $28. Percentage loss = ($28 ÷ $140) × 100% = 20%.
