Writing an equation

Question

Alexandra spent $19 at an amusement park. The admission ticket cost $7 and ride tickets cost $3.50 each. Write an equation that represents the relationship between the amount of money Alexandra spent and the number of ride tickets, t, she purchased.

Answer 1

Total Cost = 7 + 3.5T = 3.5(2+T)

C = 7+3.5T = 3.5(2+T) where T = number of ride tickets

or

Total Spent = $7 + $3.50T
