How many student tickets and how many adult tickets did the club sell? • Step 1 (understand the problem): • Ticket cost = adult $4, student $3 • Number of tickets sold: 133 tickets • Money raised=$471

  5. Step 2 (make a plan): • We are going to take a guess, and then test it. If not correct, then we use what we learned to make a better guess. • To find how much money was made on adult tickets, multiply your number by 4.
