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.

Answer:
x = 3
Step-by-step explanation:
The diagonals of a rhombus bisect each other at right angles, thus
BE = ED, that is
4x + 2 = 3x + 5 ( subtract 3x from both sides )
x + 2 = 5 ( subtract 2 from both sides )
x = 3
