A jacket is discounted 45% on Monday. It is then discounted on Friday another 20%. If the sale price on Friday (after the discount) is $31.68, what is the original cost of the jacket?
-------------------------------------
Let original price be "x".
After 1st discount: 0.55x
After 2nd discount: 0.80*0.55x
----------------------------------
Equation:
0.80*0.55x = 31.68
0.44x = 31.68
x = 31.68/0.44 = $72.00
