An online streaming service charges a monthly fee as well as a one-time sign-up fee. The cost for this online streaming service is modeled by the following function where m represents the number of months the service is subscribed to and C(m) represents the total cost given that amount of time:
C(m) = 11.99m + 7
I don't mind helping to find answers, but I resent having to provide the questions as well.
To find the cost of the online streaming service for a given number of months, you can use the given function C(m) = 11.99m + 7.
1. Start by plugging in the value of m (the number of months) into the equation.
For example, if m = 3, then C(3) would represent the cost after 3 months.
2. Multiply the value of m by the monthly fee, which is 11.99.
In our example, C(3) = 11.99 * 3 + 7.
3. Calculate the product from step 2.
In our example, C(3) = 35.97 + 7.
4. Add the one-time sign-up fee, which is 7.
In our example, C(3) = 35.97 + 7 = 42.97.
Therefore, the total cost of subscribing to the online streaming service for 3 months would be $42.97.
To calculate the total cost (C) for a given number of months (m), you can use the formula:
C(m) = 11.99m + 7
Let's walk through an example to illustrate how this formula works.
Example:
Let's say you want to subscribe to the online streaming service for 3 months. To find out the total cost, plug in the value of m = 3 into the formula:
C(3) = 11.99 * 3 + 7
= 35.97 + 7
= 42.97
Therefore, the total cost for a 3-month subscription would be $42.97.
You can use the same process to calculate the total cost for any number of months by plugging that value into the formula.
