To calculate the increase in dollars and the year-end amount for Jose's investment account, we can use the following steps:
-
Calculate the increase in amount: \[ \text{Increase} = \text{Initial amount} \times \left(\frac{\text{Percentage increase}}{100}\right) \] \[ \text{Increase} = 8600 \times \left(\frac{24.5}{100}\right) = 8600 \times 0.245 = 2107 \]
-
Calculate the year-end amount: \[ \text{Year-end amount} = \text{Initial amount} + \text{Increase} \] \[ \text{Year-end amount} = 8600 + 2107 = 10707 \]
Thus, the answers are:
- Increase in amount: $2107
- Year-end amount: $10707
