The question is
What is the constant in the expression?
we know that
[tex]c=0.05m+12[/tex]
where
c---------> the cost of Janelle’s cell phone bill
m-------> represents the number of minutes of use
[tex]0.05[/tex]-------> represent the cost per minute (slope of the linear equation)
[tex]12[/tex] -------> represent the constant in the expression
therefore
the answer is
The constant is 12
