The total amount an aerobics teacher makes for teaching x number of students can be represented by the function T(x)=4x. If T(25)=100, then teaching _ students makes the teacher _$

Teaching  25   students makes the teacher  100   dollars.

Explanation:

The notation T(25) means "The value of T(x) when x = 25".

The instructions state that x represents the number of students. So x = 25 means the teacher has 25 students.

Writing T(25) = 100 means the teacher earns $100 from teaching 25 students.

We could also write T(x) = 100 when x = 25. Though it's more compact to say T(25) = 100.

Note that,

T(x) = 4x

T(25) = 4*25 ... replace x with 25

T(25) = 100

As you can probably see by now, each student pays $4 which is what leads to the $100 total.
