That is the answer Y=x^-8x12, xER
Since he sold it for $75 more,
% Mark Up = Mark Up/ Cost Price * 100%
% Mark Up = 75 / 125 * 100%
= 0.6 * 100% = 60%
Percent Mark Up = 60%.
Hope this explains it.

If you take the numerator and the denominator from flour and multiply both by 10, you'll get 40/100. then, add 40/100 to 12/100. your answer should be 52/100. if not, look back through your math. hope that helped.
You multiply the two side lengths for area
To get 52x^3y
To find perimeter you add all the side lengths to get 8x^2+26x
