Using proportions, it is found that Talisa's error was at calculating the cost per minute of the game.
In the function:
- The input is x, which is the number of minutes.
- The output is f(x), which is the cost of playing the game for x minutes.
Talisa's expression is given by:

The cost of using a game facility is <u>$1 for every 12 minutes</u>, hence, the cost per minute is:

And the correct expression for the cost is:

Hence, it can be seen that Talisa's error was at calculating the cost per minute of the game.

Treat it like a triangle with the points at either end of the hypotenuse. Then the horizontal leg has length 7, and the vertical leg 8.
Apply Pythagoras and find length is sqrt ( 7*7+8*8 )=10.63 (or sqrt (113) if you want to be exact )
