ron and kathy are ticket-sellers at their class play, ron handling student tickets that sell for \$3.00 each and kathy selling adult tickets for \$6.50 each.
If their total income for 29 tickets was \$125.50, how many did ron sell?

if its elementary algebra don't you draw some columns and guess and test?

otherwise, these are the equations:

x(3.00) + y(6.50) = \$125.50
x+y = 29 tickets

• elementary algebra -

Let R = # tickets sold by Ron.
and K = # tickets sold by Kathy.
=================================
R+K = 29
3R + 6.50K = 125.50
=======================
Two equations; two unknowns. Solve for R and K.
