Question

How do I solve ?
Adam bought a basketball that was on sale for 25% less than the original price.The original price was $4 more than the sale price. What was the original Price?

Answer 1

p-4 = .75p
p = 16

or,

the discount is the price difference. So, .25p = 4
p=16

or

the sale price is 3/4 p, so the full price is 4/3 the sale price

4/3 s = s+4
1/3 s = 3
s = 12
so, p=s+4=16

As you see, there are usually several ways to consider things.
