Let
x--------> the number of months
y-------> represents the balance, in dollars, of a bank account
we know that
y=-50x+100
the rate of change is equal to the slope of the line
so

therefore
<u>the answer is</u>
the rate of change is 
$37.95 x12= 455.4 so Kevin’s cellphone will cost 455.4 for the year

First make and equation. Since you want to find the number of the day where both charge the same total amount, you would make the equation:
let x= the number of days
110+46(x)=70+54(x)
Solve:
110-70+46(x)=70-70+54(x)
40+46(x)=54(x)
40+46(x)-46(x)=54(x)-46(x)
40=8(x)
40/8=8x/8
5=x
Therefore your answer would be 5 days
