Warner bought 8 movie tickets for $40.00. Adult tickets sold for $5.50 and student tickets sold for $3.50. How many adult tickets did he buy?

Answer 1

This can be translated into an algebraic system of equations, then solved for Adult movie tickets

If we define adult tickets as A and student tickets as S, we can come up with 2 related equations:

A+S=8 because the total tickets sold were 8

and

5.50A+3.50S=40 when we translate the price per ticket and total cost into its equation

To solve the system, adjust the first equation to

S=8-A

Then, substitute this for S into the 2nd equation so that you can solve for A

From there, remember your PEMDAS order of operations as you solve for A
