Question 207903: I am a 15-year-old homeschool student homeschooled with the School of Tomorrow. I am doing Algebra I and am struggling with calculating questions having to do with markups, reductions and comissions. A question I am trying to solve now is "Ace bought a tennis racket for $20 on sale. This was a reduction in price of 20%. What was the regular price?" If you can show me how to solv problems such as this, I would be very grateful.

"Ace bought a tennis racket for $20 on sale. This was a reduction in price of 20%. What was the regular price?"
---------------
If it's reduced by 20%, then $20 is 80% of the original price.
Most percent problems can be done by first finding what 1% is.
In this case, $20 is 80%, so 1% is $20/80 = $0.25
100% is 100 times that.
$.025*100 = $25.
