Question

2. Given a point (x1, y1) and a slope (m)

To sign up for cable service, you must
purchase the DVR recorder upfront, then pay
$19.95 per month for service. Eight months
after signing up, Martha had paid a total of
$288.60 for the recorder and service. Write
and solve a linear equation to find the total
amount she will have paid for the 2-year
agreement she signed.

Answer 1

First, let's find the cost of the DVR recorder. Martha paid a total of $288.60 for the recorder and 8 months of service. Since the service costs $19.95 per month, the total cost of 8 months of service is 8 * $19.95 = $159.60. Subtracting this from the total amount Martha paid, we get $288.60 - $159.60 = $129 for the cost of the DVR recorder.

Now, let’s find the total amount Martha will have paid for the 2-year agreement she signed. A 2-year agreement is equivalent to 24 months. So, the total cost of service for 24 months is 24 * $19.95 = $478.80. Adding this to the cost of the DVR recorder, we get $478.80 + $129 = $607.80 as the total amount Martha will have paid for the 2-year agreement she signed.
