a) For 1 visit: $45
... For 2 visits: $45 +$45 = $90
... For 3 visits: $90 +$45 = $135
... For 4 visits: $135 +$45 = $180
... For 5 visits: $180 +$45 = $225
b) A season pass is a better deal if you visit the park 3 or more times. The cost of 3 visits without a season pass is more than the cost of the season pass. The cost of the season pass is more than the cost of 2 visits.
