The best way to solve this is to put it into a proportion:
So you cross multiply to get:
(the 21 is from
•84)
Then multiply by
And you get $28, so the reduced price would be $28.
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.
