Question 1046695
Look for how to form equations to account for cost and for distance.


How many days?  x days.
How many miles?  {{{60x(miles)}}}
Cost contribution due to distance?  {{{(0.4)*60x=24x(dollars)}}}
Cost contribution due to days?  {{{22*x(dollars)}}}


Now the thought is accounting form distance is <b>not</b> really an equation to look for.


Finishing accounting for cost,
{{{highlight_green(22x+24x=350)}}}


{{{46x=350}}}
{{{23x=175}}}
{{{x=175/23}}}
{{{x=7.609}}}
This can only be the WHOLE numbered part for count of days.
{{{highlight(x=7)}}}
