Ron and Kathy are ticket-sellers at their class play, Ron handling student tickets that sell for $2.00 each and Kathy selling adult tickets for $5.50 each. If their total income for 30 tickets was $105.50, how many did Ron sell?
a. 18 tickets b. 13 tickets c. 19 tickets d. 17 tickets
Let x be the number of student tickets. Then the number of adult tickets must be 30-x.
The total sale of 105.50 = x*(2.00) + (30-x)*(5.50)
Solve for x and then also compute 30-x.
