If 5 tickets cost $174.45 and 8 tickets cost $271.95, how much do 12 tickets cost?

Answer 1

Without making any assumptions about the problem type:

1- Test each scenario by dividing 174.45/5 and 271.95/8

2- This reveals two different answers, indicating there is an additional number being added

3- Create formulas for each scenario: # of tickets, plus added fee = total

5t + f = 174.45 8t + f = 271.95

4- Plug in both formulas into a graphing calculator and locate their point of intersect at (32.5, 11.95)

5- The X value indicates the cost per ticket, the Y value is the added fee

6- Plug in these values to find the cost of 12 tickets:

12t + f = ? 12(32.5) + 11.95 = ?

The final answer should be $401.95

Answer 2

Using a linear regression function on a calculator,

Price = 32.95 * ( number of tickets ) + 11.95

The $11.95 is a sevice fee, presumably.

12 * 32.95 + 11.95 = $401.95
