ChitChat Wireless charges $0.30 per minute plus a monthly base fee. In September, Maggie used 120 minutes and her bill was $51.
SVEN [57.7K]

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

Order 34 × 102, 1.2 × 107, 8.11 × 10–3 and 435 from least to greatest.
andrey2020 [161]
I will assume that this question is about scientific notation (also assuming that the first number is 3.4*10^2), where you can arrange the numbers by the exponent of the 10, so from least to greatest:
8.11*10^{-3}, 3.4*10^{2}, 435, and 1.2*10^{7}

Can anybody plz help me on C and D and it's due tm someone plz help
Airida [17]
0.3% = 0.003..." of " means multiply
0.003(200) = 0.6 <==

0.85% = 0.0085
0.0085(600) = 5.1 <==

what u can do to turn the percents to decimals is divide by 100.
0.3 / 100 = 0.003 and 0.85 / 100 = 0.0085
or u can move the decimal two spaces to the left
