Margo borrows $500, agreeing to pay it back with 3% annual interest after 14 months. How much interest will she pay?

She pays $17.50

Step-by-step explanation:

Interest Formula:

I = P (rt)

I = final interest

P = money borrowed

r = rate of interest

t = number of time periods

---

Plug in the values

t = 14/12 years

P = 500 dollars

r = 3% = 3/100 = 0.03

I = (500) (0.03) (14/12)

I = $17.50
