Define a variable and write an equation to model each situation. Then solve. Show your work. Tickets to the county fair for four
Citrus2011 [14]
If x is the childrens ticket
4(x + 1.5) + 5x = 33.30 \\ 4x + 6 + 5x = 33.3 \\ 9x = 33.3 - 6 \\ 9x = 27.3 \\ x =  \frac{27.3}{6}  \\ x = 4.55
so that means that the adults ticket is
x + 1.50 = 4.55 + 1.50 = 6.05
