Mark’s new car is a lemon. It breaks down within 6 months of purchasing the car. Mark cannot afford the repairs so he charges $2,000 in car repairs on the store account and plans on paying a minimum monthly fee of $50. The card carries a 25% Annual Percentage Rate (APR). How much are those car repairs really costing Brent and when will he pay off the amount owed?

Answers

The worth of the repairs is actually $3,686.25 and the amount will be paid off after 6.07 years. This is assuming that the APR is effective and compounded per year.
The $50 can be converted to a Future Value per year before the rest of the given can be used.

How do i find the slope of a line that passes through a given point and is parallel or perpendicular to another given point?

Answers

There's no such thing as parallel or perpendicular "to a point". A problem like that
will always want the new line to be parallel or perpendicular to another line.

-- If the new line is parallel to the given line, then they have the same slope.

-- If the new line is perpendicular to the the given line, then the slope of the
new line is [ 1 / slope of the given line ].

In either case, you now have the slope of the new line and a point on it.
From there, you should have no trouble finding its equation.

Parallel is same slope.
Perpendicular is same slope but you have make it opposite and flip it.
For example if your slope is 2/3. For Perpendicular it would be - 3/2.
