Mr. Accardi sold 600 tickets for the high school play. If adult tickets cost $6.00 each and student tickets cost $4.00 each, how many of each type of ticket did he sell if $2,900.00 was collected in ticket money?

Given:

Total number of tickets = 600

Cost of adult ticket = $6.00

Cost of student ticket = $4.00

Total sales = $2900.00

To find:

The number of tickets of each type.

Solution:

Let the number of adult tickets be x and number of student tickets be y.

According to the question,

       ...(i)

     ...(ii)

Multiply equation (i) by 4 and subtract the result from (ii),

Divide both sides of 2.

Put x=250 in (i).

Therefore, number of adult tickets is 250 and number of student tickets is 350.
