ok so differnce of 2 perfect ssquares are
x^2-y^2=(x-y)(x+y)
we are given
one factor is 5x-8
remember that all you do is square both terms individually to get them
(5x)^2=25x^2
8^2=64
they are difference so
25x^2-64 is answer
Use ratio and proportion
$23/$x=63%/100%
cross multiply
63x= 2300
divide
x= $ 37.50 selling price
hope this helps
In word problems, the word 'of' almost always means 'multiply'.
1/2 *of* 1/5
1/2 = 0.5
1/5 = 0.2
0.5 * 0.2 = 0.1
0.1 = 1/10
