Question

need help: Yuko bought a pair of pillowcases that cost her a total of $24.90. She got the pillowcases on sale at 15% off and paid a state sales tax of 8%. What was the original price of the pillowcases?

Answer 1

Let the money she paid be x
then, x - 15 % of x + 8 % of x = 24.90

Answer 2

Using what shubham said, remember that "of" means times and to make % into decimals... except that the sales tax would have been on the reduced price, so:

Answer 3

x-.15x = .85x for the reduced price
and then sales tax is the total (100%) plus 8%:
1.08(.85x)=24.90
and solve

Answer 4

where do u get .85x? I'm not clear for that.

Answer 5

OK, 15% off is the total, or 100% minus 15% for 85% remaining

Answer 6

so if the price was x, then the reduced price you get by subtracting 15% of x is the same as finding 85% of the original price, x.
1.00x - .15x = .85x
100% minus 15% = 85%
