Answer: Victor's annual income after 12 years as a teacher would be $47,564 if he received an average 4 percent raise every year.
The accumulated future value of earning $3,000 each year teaching during the summers over 12 years with a 5 percent raise every year would be $41,592.
Explanation:
To calculate Victor's annual income after 12 years as a teacher, we need to find the future value of his starting salary of $40,000 after 12 years with an average 4 percent raise every year.
Using the formula for the future value of a single amount (FV = PV * (1 + r)^n), where PV is the present value, r is the interest rate, and n is the number of years, we can calculate the future value as follows:
FV = $40,000 * (1 + 0.04)^12 = $47,564
So, Victor's annual income after 12 years as a teacher would be $47,564 if he received an average 4 percent raise every year.
To calculate the accumulated future value of earning $3,000 each year teaching during the summers over 12 years with a 5 percent raise every year, we need to use the formula for the future value of a series of equal amounts (FV = A * (1 + r)^n - 1 / r), where A is the annual payment and r is the interest rate.
Plugging in the values, we get:
FV = $3,000 * (1 + 0.05)^12 - 1 / 0.05 = $41,592
So, the accumulated future value of earning $3,000 each year teaching during the summers over 12 years with a 5 percent raise every year would be $41,592.
