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. 2. angelrenee2000 says: 122 Minutes Step-by-step explanation: Start with$16.42

subtract $3 for the monthly fee, 16.42-3=$13.42

he pays $0.11 per minute so that's 13.42 x (1min/0.11) = 122minutes 3. danielleen731 says: The number of minutes for which Keith was billed = 97 Step-by-step explanation: Step 1: It is given that Keith pays a fixed fee of 3$ a month and 11 cents per minute  for the number of minutes used.

Total cost = Fixed cost + Per minute cost

If x represents the number of minutes consumed in a month then we can compute the total cost using the below equation:

Total cost = 3$+ 0.11 * x Step 2: The total cost is 13.67$

Substituting in the equation we get

13.67 = 3 + 0.11 * x

x = 10.67 / 0.11 = 97 minutes

Step 3:

The number of minutes for which Keith was billed = 97

He was billed for 97 minutes.

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

Keith used his long distance phone service for 97 minutes.
