Answer:
$C = 0.30(m) + 15
C is bill cost
m is number of minutes used
Step-by-step explanation:
In this question, we are asked to write an equation that estimates the bill cost of Maggie’s phone bills.
We proceed as follows;
Now, let’s try and find the base fee.
We can calculate this using her bill for September.
Mathematically;
Bill = (Cost per minute * total minutes) + Base fee
Here, $0.30 per minute for 120 minutes will yield a total of 120 * 0.3 = $36
This means the base fee would be $51-$36 = $15
Now let’s say the bill is $C, and the number of minutes used is m
Mathematically;
$C = 0.30(m) + 15
