A cellular phone company charges a $25 monthly fee and an additional $0.10 per minute. If m represents the number of minutes of phone usage, which equation can be used to determine the total monthly cost, c?

Respuesta :

Answer:

c= 0.10m+ 25

Step-by-step explanation:

using the format y=mx+b

25 is your flat cost that they charge every month, and 0.10 is what they charge per minute.

m is the number of minutes so that is the unknown variable.

c is your total cost.

you take the flat cost per month (25 dollars) and add it to however many minutes multiplied by 0.10 (.10m)
