Answer:
The sale is 5% off.
Step-by-step explanation:
- $25 regular price.
- $18.75 sale price.
You need to find the percentage that deducts $1.25 from the regular price. I start with 5% and work my way up from there until I find the answer.
So, <em>5</em><em>%</em><em> </em><em>of </em><em>2</em><em>5</em><em> </em><em>=</em><em> </em><em>?</em>
5% * 25 = 1.25
You needed $1.25, 5% gives you that.
Therefore, the answer is 5%.
