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 .

=$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

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
