Marina Koch · Answer 1

Subtract the sale price from the original price then divide the difference by the original price.

Guitar 1: 160 - 100 = 60

60/160 = 0.375 x 100 = 37.5%

Guitar 2: 250 - 150 = 100

100/250 = 0.4 x 100 = 40%

The answer is the second guitar has a greater percent change of approximately 40%
