Question

The school choir is selling tickets for $6 each to a choral performance to help pay for a trip to New York. The choir needs to make $1,500 for the trip and they have already sold $300 worth of tickets. How many more tickets do they need to sell?

Answer 1

The answer is 200 more tickets

Answer 2

200 tickets.

Explanation:

Set the equation. Let the variable t = tickets:

6t + 300 = 1500

To break down the equation:

6t → Remember, t is the variable denoting tickets. Each ticket costs $6, therefore, you multiply the amount of tickets (t) with the cost (6): 6t

300 → The choir had already sold $300 worth of tickets. This amount will not change.

1500 → The amount the choir needs to go to New York.

Solve. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, Subtract 300 from both sides:

6t + 300 = 1500

6t + 300 (-300) = 1500 (-300)

6t = 1500 - 300

6t = 1200

Next, divide 6 from both sides:

(6t)/6 = (1200)/6

t = 1200/6

t = 200

200 tickets more is your answer.
