A family pays $8.00 to park at a concert. Tickets for the concert cost $13.50 per person. The family spent a total of $89.00 for parking fees and tickets to the concert. The situation can be modeled by the equation 89 = 13.5n + 8, where n represents the number of tickets purchased. How many concert tickets did the family purchase?

Question

willt · Answer

$$89=13.5n+8$$
Is what you would have as your equation. We need to isole the variable, n. To do this, we first subtract the 8 from the 89.
$$81=13.5n$$
Now to isolate the n we need to divide 81 by 13.5.
$$6 = n$$
Assuming n represents the tickets purchased, the answer would be 6. It's all about isolating the variable.
