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?

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

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.
