You will definitely want a calculator for this one if it is allowed.
5.6x = 39.76
To solve for x, you need to divide both sides of the equation by 5.6 to leave only x on the left.
x = 39.76/5.6 (Reduce this)
x = 7.1
Check your work.
5.6 (7.1) = 39.76 Yes. It checks.
Answer:
Step-by-step explanation:
The plan is
$40 a month for 600 free minutes.
For each extra minute
10 cents are charged.
So the cost function is a piecewise function, that is, it has one definition if the number of minutes is below 600 and one if above.
Below 600 minutes
No matter the number of minutes, you will pay 40. So
Above 600 minutes
For the first 600 minutes, you pay just $40.
For each extra minutes above 600, you pay $0.1l, on top of the initial $40. So
Write the monthly cost C (in dollars) as a function of the number x of minutes used.
