Let's create two equations and solve them using the substitution method.
- where s = student tickets and a = adult tickets.
Solve the first equation for s. Subtract a from both sides.
- s = 26 - a
Plug s into the second equation.
- (26 - a) + 3.5a = 46
- Combine like terms.
- 26 + 2.5a = 46
- Subtract 26 from both sides.
- 2.5a = 20
- Divide both sides by 2.5.
- a = 8
Plug 8 for a into the first equation.
- s + (8) = 26
- Subtract 8 from both sides.
- s = 18
Since Ron handled student tickets, he sold 18 tickets (s = student tickets = 18).
