Answer:
c = 9
Step-by-step explanation:
9c - 10 = 2c + 53
9c =2c + 63
7c = 63
c = 9

Numerator is 3 and denominator is 5. So, we divide the sales price by 3 and we multiply by 5 to get the whole fraction, or 100%.

Your regular price sounds recurring, so you might have made a mistake copying.
The answer for what you've got is 94.633333...
-2+4-3+8-2-0.5 = -7.5+12
-7.5+12 = 4.5
4.5/6 (number of months) = 0.75
0.75 = -3/4
-3/4 is your answer. :)
