The senior class is taking a trip to an amusement park. They received a special deal where for every 3tickets they purchased they received one free ticket. 3 tickets cost $53.25. The total purchase of tickets cost S1384.50. How many tickets did they receive?

1384.5 divided by 53.25 = 26. 26 * 4 = 104. The answer is 104.

Since we know that 3 tickets = 53.25 we take the total amount spent and divide by the price for 3 tickets. This gives us 26 which means they purchased 3 tickets twenty six times. However we also know that they received a fourth ticket every time they purchased three so we multiply 26 by 4 (instead of 3) which gives us 104.

They received 26 free tickets. Divide 53.25 into 1384.50 which will give you 26.
