the ABC cell phone company offers a plan that includes a flat rate fee of $29 per month plus a $0.12 charge per minute.write an equation to find C, the total monthly cost for m mintues. then solve the equation for m=50. please show work.
C = 29 + 0.12 m
is the equation.
Substitute 50 for m and solve for C
C = 29+0.12m; C = 35
M=35
C=29+0.12m
29+0.12(50)
29+6
C=35
To find the total monthly cost, we need to take into consideration the flat rate fee of $29 per month and the charge per minute.
The equation to find the total monthly cost, C, for m minutes is:
C = 29 + 0.12m
To solve the equation for m = 50, we substitute the value of m into the equation:
C = 29 + 0.12 * 50
First, multiply 0.12 by 50: 0.12 * 50 = 6
C = 29 + 6
Next, add 29 and 6 together: 29 + 6 = 35
Therefore, when m = 50 minutes, the total monthly cost, C, is $35.
