An amusement park has two types of season passes. Plan 1 costs a one-time fee of $129.00 for admission plus $7.00 every trip for parking. Plan 2 costs a one-time fee of $50.00 for parking plus $22.00 every trip for admission. At about how many days are plan 1 and plan 2 equal in value?
If the number of trips is set as n, Plan 1 costs 129+7n and Plan 2 costs 50+22n. If you set these equal to eachother and solve, you will find the number of trips after which the Plans are equal in value. 129+7n=50+22n 79=15n n=79/15
