Question

Marc sold 425 tickets for the school play. Student tickets cost $4 and adult tickets cost $5. Marc's sales totaled $1925. How many adult tickets and how many student tickets did Marc sell?

Answer 1

Answer: a=225 adult, s=200 student

Explanation: We need a system of equations to find how many of each ticket Marc sold and we can use 4s+5a=1925 and s+a=425.

If we isolate a, we will have a=425-s

If we plug this into the first equation, we will get 4s+2125-5s=1925

Solving for s gives us s=200.

To find a, we can do 425-200 to find that a=225.
