2. If 
then
3. Hence,
First, multiply 4*2x-4*-5= 8x-20.
Second, add 15 to 8x-20
Third, that would equal 8x-20+15=11
Fourth, 15+-20= -5
Fifth, 8x-5=11
Sixth, add +5 to -5 and +5 to 11= 8x=16
Last, do 8x/8x and 16/8x
The answer is x=2
So you do $90 times .40 because 40%=.40 then next you set up your problem
90x.40=36
In total the sales price is $36
