ChitChat Wireless charges $0.30 per minute plus a monthly base fee. In September, Maggie used 120 minutes and her bill was $51. WRITE an equation to find the cost if Maggie uses any number of minutes.

$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

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

16 is the absolute value
