Question

Each month, a phone company charges $30 talk time plus $0.50 for each additional minute.

Answer 1

Answer:

30+.50m=c

Step-by-step explanation:

30 is the initial cost. Since its initial it is only a one time fee.

.50 is the cost per minute, since it says per you can automatically assume that it will be more than once.

M represents the minutes that they spend on the call, so if there was a 10 minute call, instead of m you would put 10, 10×.50.

But since there is no given time we have to put a variable, m, as a replacement.

The c is the variable for the cost.

Answer 2

Answer:

Step-by-step explanation: If 1 minutes of talk = 30 and texting = 30

and each additional minute of talk = 0.50

 

then the bill would be (for C = total cost)

 

C = 20+30+(0.45 • x)

 

OR

 

C = 50 + 0.45x
