Question

MEDALS!!!!!!!
A landscaper charges a one-time fee of $70 plus $45 for each hour on the job. If t is the number of hours on the job and f is the total fee for the work done, then the variables are related by the equation f = 45t + 70.



Which variable is the independent variable?

A.
There is no relationship between the variables.







B.

f








C.

t

Answer 1

The independent variable is the coefficient. That's how I would think of it. Whereas, the dependent variable is the one that is depending on the independent variable to give it a number. In this case,the coefficient is 45t making 't' the independent variable and the one that is relying on 't' is 'f'.

Answer 2

so the answer would be ....B?

Answer 3

No, read my reply carefully. It says that 't' is the independent variable. :)

Answer 4

thx

Answer 5
