Worksheet Activity
Solve a system using tables.
a. Blue Lake is Pat’s favorite place to swim during the summer.
There is an entry fee of $12.00 per car per day. Pat notices a sign
as they approach the entrance. His family could join the Blue
Lake Club for the summer! It costs $48.00 to join and then the
entry fee becomes $6.00 per car per day. Fill in the table to help
you develop the equations.
Days at the
Lake
Cost Without

Cost With
Membership
1 $12(1) = $12 $48 + $6(1) = $54
2 $12(2) = $24 $48 + $6(2) = $60

b. Let C = the entry cost to the lake. Let D = the number of days
Pat’s family goes to the lake during one summer. Write the system
of two equations that describe the cost of the entry fee without
membership and with membership. Use the table above (in part
a) to help you write the equations.
Cost Without Membership: _______________________________
Cost With Membership: ________________________________
