At the corner market it costs $4.32 for a dozen apples. How much would it cost if I bought five apples?

so do $4.32 divided that by 12 and you will get a new number and then you take ur new number and times that by 5.

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
