Tracie buys tickets to a concert for herself and 2 friends. There is an 8% tax on the cost of the tickets and an additional $10.00 booking fee. Write an algebraic expression to represent the cost per person. Simplify the expression, if possible. Define what the variable represents and identify the units for the expression.

Total number of people going to the concert = 3 (Tracie + 2 friends)

Tax = 8% on cost of tickets

Booking Fee = $10

Let base cost of each ticket be x

Algebraic Expression:

So cost per person for the concert ticket = x + (8% * x) + 10

Simplified Expression:

Cost per person for the concert ticket = (1.08 * x) + 10

The variable 'x' here represents the base cost of the ticket (excluding tax and booking fee)

The units of the expression would be $, since all are monetary values
