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
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.
thank u guys!
