Using the function concept, a teacher's hobby cannot be represented as a function of the subject that teacher teaches, as <u>teachers of the same subject can have different hobbies</u>.
<h3>What is a function?</h3>
- In a function, <u>one value of the input can be related to only one value of the output.</u>
<u />
In this problem, the input is the teacher's subject, while the output is the hobby. As there can be teachers with the same subject but different hobbies, one value of the input would be mapped to multiple outputs, hence the situation cannot be represented by a function.

Answer:
$7.25 = 2.5, so divide by 7.25 by 5 = 1.45 <- better deal & $0.46333333333 per litre.
5.74 = 1.5, so divide 5.74 by 3 = 1.91333333333
Step-by-step explanation:
Why 3 and 5 - 0.5 is 5 times 2.5 and so is 0.5 times 3= 1.5
1.91333333333 - 1.45 = $0.46333333333 per litre.
