Question

Jacob rents tablecloths from two companies. The first company charges $18 for an initial fee and $3 per table cloth, and the second company charges $20 and $2 per table cloth.

Answer 1

A. two table cloths

B. 24$

Explanation:

First, develop your functions:

`f(x)=3x+18\\g(x)=2x+20`

f(x) is the first company, g(x) is the second company.

A.

Set the two equations to be equal to each other and solve for x:

`f(x)=g(x)\\3x+18=2x+20\\3x-2x=20-18\\x=2\\`

B.

Just plug in the value you got from A into either function:

`f(2)=3(2)+18\\f(2)=24`
