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:
Option D. c = 45 will be the answer.
Step-by-step explanation:
In the figure attached there are two similar parallelograms PARL and WXYZ.
In which AP = 15, PL = 40, WZ = 120 and WX = c
By the property of similarity, corresponding sides of the given parallelograms will be in the same ratio.
c = 
[By cross multiplication]
c = 45
Therefore, Option D. c = 45 will be the answer.

Answer:
r = -1/2
Step-by-step explanation:
3(5 + 4r) = -18r
15 +12r = -18r by distributive property
15 = -12r - 18r
15 = -30r
r = - 1/2r
