Use reasoning to lead to the answer of the following question:
There are 30 major league baseball stadiums. Zach has a goal to take his son to see at least one game at each one. He has calculated the average cost for them to travel and see a game will be $900 per stadium. Zach can save $1,500 per year for his baseball stadium trips. How many years will it take Zach to accomplish his goal?

18
The total cost would be $900 x 30 stadiums = $27,000.

Dividing the total cost by the amount Zach saves per year, we get $27,000 / $1,500 / year = 18 years.

.

Therefore, the answer is 18
