The Olson's spend 33 1/3% of their take home pay on mortgage payments. If their take home pay is $1,689 a month, what is their monthly mortgage payment?

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
