Lana is deciding whether to buy a pool pass for the summer.
A pass costs $40.00 and $1.00 for admission each day. Without a pass, the cost is $5.00 per day.
Use the system of equations below to find out the number of days, d, for which the cost will be the same whether she decides to get a pass or not. Show your work.
c = d + 40
c = 5d
