To calculate the total annual return on Kate's investment, we need to determine how much profit she made over the course of the year (including both the change in the stock price and the dividends) and express that as a percentage of the original purchase price. Then, we'll convert that into an annual effective rate.

Step-by-Step Calculation:

1. Initial Purchase Price:

Kate bought the stock for $P_0 = 99$.

2. Price and Dividend at 6 months:

• After 6 months, the stock price was $P_{6m} = 112$.
• A dividend of $D_{6m} = 7$ was paid at that time.

3. Price and Dividend after 1 year:

• After 12 months (1 year), the stock price was $P_{1y} = 116$.
• A dividend of $D_{1y} = 5$ was paid at that time.

4. Total Return (Profit):

• The price change after one year is:
  $P_{1y} - P_0 = 116 - 99 = 17$.
• Total dividends received during the year:
  $D_{6m} + D_{1y} = 7 + 5 = 12$.
• Total profit (capital gain + dividends) is:
  $17 + 12 = 29$.

5. Rate of Return:

• The total return over one year is the profit as a percentage of the initial purchase price: $\text{Total return} = \frac{29}{99} = 0.2929 \approx 29.29\%$

Thus, the total annual return on Kate's investment is approximately 29.29%, expressed as an annual effective rate.
