After 15% off, the book price becomes $26, what was the original price of the book? Round to the nearest cent. I had $29.9 but it was wrong :(
0.85x = 26
Solve for x.
I can't. I keep getting the same 3.90 over and over again!
I don't get it!
0.85x = 26
Divide both sides by 0.85
x = 26/0.85
x = 30.588 = $30.59
Thanks, 26/.85
You're welcome.
Let x = price of the book before discount
x-0.15x = 26
1x-0.15x = 26
0.85x = 26
x = 26/0.85
Punch in 26 on the calculator, hit the divide button, type in 0.85 and hit the enter = button.
