The cost of using a game facility is $1 for every 12 minutes. Talisa writes the function for the cost per hour as ()=. Explain T
Anna [14]

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 <u>$1 for every 12 minutes</u>, 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.
