suppose that a cell phone plan charges $15 for the first 60 minutes or less used in a month and $0.50 for each additional minute. Write a piecewise function that shows the charges for time t where t ranges from 0 to 63 minutes

Respuesta :

f(x)=15 when x≤60
     =.5(x-60)+15  when x>60

The amount that will be charged for someone who uses 63 minutes will be $16.5.

Based on the question given, the equation to solve the question will be:

= 15 + (0.5t)

In this case, we are told that the person spent 63 minutes, then the number of extra minutes will be 63munutes - 60 minutes = 3 minutes

Then, the equation will be:

= 15 + (0.5t)

= 15 + (0.5 × 3)

= 15 + 1.5

= 16.5

Therefore, the amount that will be charged for someone who uses 63 minutes will be $16.5.
