Roger is buying a new pair of shoes for 25% off. if the original price of the shoes was $80.00, how much money is roger saving on the shoes?

Well, we know that 25% is also 1/4 and if we multiply $80.00 by 1/4 you get $20 so the answer is $20.

First, you would need to create an equation for this problem. Remember, 25% = 0.25
0.25 × $80.00

Now, all you would need to do is solve it. 
0.25 × $80.00 = $20.00

Roger is saving $20.00. 

I hope this helps!
