Question

3. A 12 % discount on a pair of washer and dryer that Gayle purchased, amounted to $156.00.

Calculate the net price.

Answer 1

For this case we know that the price after the 12% of discount is 156 and we want to findd the net price so then we can use the following proportional rule:

`(x)/(100) = (156)/(100-12)`

Where x represent the net price. And if we solve for the value of x we got:

`x= 100 *(156)/(88)= 177.273`

So then the net price for this case would be $ 177.273
