Problema Solution
Salisbury High School decided to take their students on a field trip to a theme park. A total of 150 people went on the trip. Adults pay $45.00 for a ticket and students pay $28.50 for a ticket. How many students and how many adults went on the field trip if they paid a total of $4770.00?
Answer provided by our tutors
the number of adult tickets= x
the number of student tickets=y
45x +(28.50)y=4770
x+ y=150
y = 150 - x
substituting for y:
45x + 28.50(150-x) = 4770
45x-28.5x + 4275=4770
16.5x=4770-4275
x=(4770-4275)/16.5
x=30
y=150-x=150-30=120
therefore 30 adults and 120 students attended
