Question

I need help with this problem

Answer 1

I would reccomend the author go with company B, as they are about 7 cents cheaper than company A when needing to get 100 books printed.

Explanation:

To get to this answer, we can simply solve both expressions we are given by setting x=100, as this is the number of copies that are needed.

`Company A: (120+4x)/(x) =(120+4(100))/(100) =(520)/(100) =$5.20 for 100 copies`

`Company B: (25+10x)/(2(x)) =(25+10(100))/(2(100)) =(1025)/(200) = $5.13 for 100 copies`

As we can see here, company B is 7 cents cheaper than company A for 100 copies.
