Total cost of the shirt from
eBay is the price of the shirt plus the shipping:
19.99 + 1.50 = $21.49
Find the cost difference:
50 - 21.49 = $28.51
Divide the cost difference by original price:
28.51/50 = 0.5702
Multiply by 100 to get percent:
0.5702 x 100 = 57.02%
Answer: 57.02% ( you can probably round the answer to 57%)
