Question

Gina loaned Gerry $300 at an interest rate of 10 percent a
year. How much interest will Gina get if Gerry pays Gina after
6 months?

Answer 1

To find the interest, we need to calculate half of a year's interest because Gerry paid after 6 months.
Half a year's interest = (10/100) * $300 = $<<10/100*300=30>>30.
Therefore, Gina will get $30 interest if Gerry pays Gina after 6 months. Answer: \boxed{30}.
