Question

Airline fares are $200 for first class and $150 for business class. If a flight had
52 passengers who paid a total of $8500. How many first class passengers.
we’re on the trip?

Answer 1

Answer:

• 14 first class passengers

Step-by-step explanation:

Set a system of equations as below:

• x + y = 52
• 200x + 150y = 8500

Multiply the first equation by 150 and subtract from the second equation.

This will eliminate y, solve for x:

• 200x + 150y - 150x - 150y = 8500 - 150*52
• 50x = 700
• x = 700/50
• x = 14
