Question

Each month, a phone company charges $20 for 500 minutes of talk time plus $0.45 for each additional minute. Unlimited texting costs $30 more. Choose an expression to show the cost of a talk-and-texting plan for one month, given x minutes over 500.

Answer 1

Answer:

The correct answer is:

C = 20+30+(0.45 • x)

OR

C = 50 + 0.45x

Step-by-step explanation:

If 500 minutes of talk = $20

and texting = $30

and each additional minute of talk = $0.45

then the bill would be (for C = total cost)

C = 20+30+(0.45 • x)

OR

C = 50 + 0.45x

Hope this helps!! :)
