Question

Netflix charges David $15 per month for a membership, plus a one time $5 fee to stream on his phone. How many months will David have his membership if Netflix charges David $50?

Answer 1

David will have his membership for 3 months.

Explanation:

For the first month + the one-time mobile fee, that is $15 for one month + $5 for the fee.

So far, he has been charged $20.

Another month's cost is $15 more, which will bring his total cost to $35.

Another month's cost is $15 more, which will bring his total cost to $50.

If Netflix charges David $50, that means he will have paid the mobile fee, and have had his membership for 3 months.
