Step-by-step explanation:

First, subtract 3 from 13.67 so we can find out the minutes only and not the minutes along with the monthly bill.

This will come out to be 10.67

Now, we will divide 10.67 by .11

          This will come out to be 97.

This means he was billed for 97 minutes on the phone

Hope I helped!

Please tell me if this is wrong and my most sincere apologies if it is.

<h3>Answer:</h3>

<u>He was billed for 97 minutes.</u>

Step-by-step explanation:

Knowing that Keith's plan has a $3 base fee and takes 11 cents per minute, we  can start by removing the $3 from the equation since we are looking for the amount of minutes he was billed for.

$3 + $0.11x = $13.67 ---> $3 (-$3) + $0.11x = $13.67 (-$3)

---> $0.11x = $10.67

Next, divide both sides by 0.11.

$0.11x = $10.67 ---> $0.11x ÷(0.11) = $10.67 ÷(0.11) ---> x=97

<em>Keith used his long distance phone service for 97 minutes. </em>

Mars2501 [29]

Answer:

Step-by-step explanation:

We know that the break even point is the point where the cost and the revenue equations intersect.  So the break even point in this situation is:

C= R

<=> 20/3x+50 = 10x (with x > 0 and x is a whole number)

<=> 10x^{2} -50x -20 = 0

<=> x ≈ 5

If the company sells more than 5 items, it will have benefit

If the company sells less than 5 items, it will lose
