Answer:
Step-by-step explanation:
What you are asking is to fill in the blank in the following sentence.
_______ % off this imported futon.
Solution
500 x/100 = 425 Divide the left by 100
5x = 425 Divide both sides by 5
5x/5 = 425/5 Simplify
x = 85
That is not the answer. That is the % paid.
The reduction is 100% - 85% = 15%
So your blank would contain 15%
Check
15% of 500 = 15/100 * 500 = 75 which is what they the store is offering you off.
