Question

The cost of using a game facility is $1 for every 12 minutes. Talisa writes the function for the cost per hour as ()=. Explain Talisa’s error.

Answer 1

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:

$f(x) = 12x$

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

$c = \frac{1}{12}$

And the correct expression for the cost is:

$f(x) = \frac{x}{12}$

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