Tina borrowed some money at 6% simple interest and paid it back exactly seven years later by making a single payment of $4544. How much did she borrow in the first place?

To find out how much Tina borrowed in the first place, we can use the formula for simple interest.

The formula for simple interest is:
Interest = Principal * Rate * Time

In this case, Tina paid interest for seven years and made a single payment of $4544. Let's call the principal, or the amount she borrowed, P. The rate is given as 6%, which is equivalent to 6/100 or 0.06. The time is given as seven years. The interest can be calculated using the simple interest formula:

Interest = P * Rate * Time

$4544 = P * 0.06 * 7

To find P, we need to isolate it on one side of the equation. Divide both sides of the equation by (0.06 * 7):

P = $4544 / (0.06 * 7)

P = $4544 / 0.42

P ≈ $10,827.62

Therefore, Tina borrowed approximately $10,827.62 in the first place.
