Answer:
25%
Step-by-step explanation:
3/12 = 0.25 = 25%
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%
Factor it out (x+2)(x-1)
Set each of these equal to zero to get -2,1 as your answers
