Answer:
432 bicycles
Explanation:
In this question, since we are told that every bike rack holds 18 bikes and are also told the total amount of bike racks available then we can easily solve for the total amount of bicycles that can be stored by multiplying both of these values together.
24 * 18 = 432 bicycles
All the bike racks on the campus and park can hold a total of 432 bicycles.
