Answer:
Money save =$212.50
Step-by-step explanation:
Given : After a 20% sale discount, Frank Purchased a new refrigerator for $850.
To find : How much did he save from the original price.
Solution : We have given
Sale discount = 20 % .
Paid percentage 100%-20% = 80%.
Money pay = $ 850 .
Let the original price = x
80% of x = $850 .
[tex]\frac{80x}{100}[/tex] =$850 .
80x = 85000.
On dividing both sides by 80.
x = $1062.5
Original price = $1062.5
Money save = 1062.5 - 850 = $212.50
Therefore, Money save =$212.50
