What is a linear function?
A linear function is given by 'y = mx + b
where m is the constant rate of change and 'b' is the value of function y when x = 0
For given example,
the function y = 0.05x + 25 represents the monthly charges for a cell phone where x is the number of minutes used.
if the phone is not used during the month, then the number of minutes phone used (x) = 0
Using the given linear equation the amount of bill would be,
⇒ y = (0.05 × 0) + 25
⇒ y = 0 + 25
⇒ y = 25
Therefore, if the phone is not used during the month then the amount of bill = 25
The correct answer is option (D) 25.00
