Question

Trey pays a $6 monthly fee plus 8. Cents per minute. Last month, Trey's long distance bill was $12.72. For how many minutes was Trey billed

Answer 1

Hello!

Since Trey pays a flat monthly $6 fee, we can subtract that from the total bill:

$12.27 - $6 = $6.72

That leaves us with a total of $6.72 paid for minutes. We are told that Trey is charged 8 cents per minute of usage. Using the information above, we can create the following equation:

$0.08 x (minutes) = $6.72

Now divide $0.08 from both sides of the equation and simplify:

$\frac{0.08}{0.08}$ x (minutes) = $\frac{6.72}{0.08}$

minutes = 84

We have now proven that Trey was billed for 84 minutes.

I hope this helps!
