(6x-2)(6x-2) = 36x-12x-12x+4 = 36x+4
To determine the percent change in price, solve for the differences between the original prices and the sale prices. Then, divide the difference by the original price and multiply by 100%.
Guitar 1: (($160 - $100) / $160) x 100% = 37.5%
Guitar 2: (($250 - $150) / $250) x 100% = 40%
Thus, guitar 2 has a greater percent change in price.
If 12 is shaded out of 18 then the fraction is 12/18. We then need to simplify it to get 2/3.
The answer is D) 2/3
