If you would like to know what do the f(x) and x represent in Luke's situation, you can find this using the following step:

<span>f(x) = 7x + 15
</span>7 hours each week
x ... the number of weeks
f(x) ... the total number of hours Luke exercises

The correct result would be A) <span>f(x) represents the total number of hours; x represents the number of weeks he exercises this summer.</span>
