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

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:

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

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

Step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

2 x t divided by n
