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?(1 point)
If the interest rate on the loan is 10 percent per year, then the interest rate for 6 months would be half of that, or 5 percent.
The interest earned on the loan would then be $300 x 0.05 = $<<300*0.05=15>>15. Answer: \boxed{15}.
