How to Maximize Small Bus Rentals for a Trip
Assuming a number of small buses are rented as 'a', then the number of large buses will be '11 - a'.
Therefore, we have the inequality:
18a + 35(11-a) ≥ 300 + 30
Solving this inequality, we get:
a ≤ 55/17
Since 'a' must be an integer, the maximum value of 'a' is 3.
Therefore, the maximum number of small buses that can be rented is 3.
