Question 1153322

Using the equation {{{y = 45+30x }}}if an electrician works {{{3}}} hours on a job, how much will the bill be?

{{{y = 45+30x }}}......if {{{x=3}}}, we have
{{{y = 45+30*3 }}}
{{{y = 45+90 }}}
{{{y = 135 }}}

Using the equation {{{y = 45+30x}}}, if you have a budget of {{{300.00}}} dollars for this job, what is the most full hours the electrician can work? 

{{{y = 45+30x }}}......if {{{y=300.00}}}, we have

{{{300.00 = 45+30x }}}

{{{300.00 -45=30x }}}

{{{255=30x }}}

{{{x=255/30}}}

{{{x=8.5}}}->the most {{{full}}} hours the electrician can work is {{{8}}} hours
