Question 1132965
x miles
b daily fee
{{{y=mx+b}}}{{{cost}}}


The two described cost equations would be
{{{system(90=(m)(300)+3*b,162=(m)(600)+5b)}}}
Simplify and solve the system for m and b.
(Or you might want to first solve for b by elimination.)

{{{system(300m+3b=90,600m+5b=162)}}}


{{{system(600m+6b=180,600m+5b=162)}}}


{{{E1-E2}}}
{{{highlight(b=18)}}}----------daily fee
