School Field Trip Budget Calculation

A group of students went on a field trip. If each bus can hold 25 students and there were a total of 5 buses, how many students can be accommodated?

On the trip, each student brought lunch, an apple, and a drink. The total cost for lunch per student is $5, the cost for an apple is $1, and the drink costs $2. If the school budget allocated $1,500 for this trip, how much money will be left after covering the total costs for the lunches, apples, and drinks for all students?
