Answer 2

The constant in the expression is 12

Explanation:

The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can be written as :

f(m)=0.05m +12

Example if m is 1 or 2

f(1) = 0.05(1) +12 = 12.05

f(2= = 0.05*2 +12 =0.1 +12 = 12.1

The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.
