Answer

To find out how much more June should have invested, we use the simple interest formula: I = PRT, where I is the interest, P is the principal amount, R is the rate of interest per year, and T is the time in years.

June wants to earn $6,500 in interest over 11 years at a rate of 2.6%.

First, calculate the total principal needed:

6500 = P * 0.026 * 11

P = 6500 / (0.026 * 11) = 6500 / 0.286 = 22,727.27

June initially invested $17,801, so the additional amount needed is:

22,727.27 - 17,801 = 4,926.27

To the nearest dollar, June should have invested $4,926 more.

The correct answer is d. $4,926.
