Period: ____
Jim Nasium is a personal trainer. He charges each client an initial fee of $15 for training. Then
he charges $20 for each hour. Let x represent the number of hours a client is working out and
let y represent the total money Jim collectes from each client.
1) Complete the table of values to show the total cost of each month for Jim Nasium.
x, hours

y, total cost
2) Represent Jim Nasium’s situation as a graph.
Remember to:
–label your axes
–include a title
–choose and label an appropriate
scale on the x– and y–axis.
3) Represent this situation as an equation in slope–intercept form.
