Using an exponential function, it is found that:
a) The doubling time of the salary is of approximately 20 years.
b) The salary will be of $160,000.
<h3>What is an exponential function?</h3>An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
The growth rate for this problem is:
r = 0.035.
The doubling time is t for which A(t) = 2A(0), hence:
t = 20 years.
You retire in 40 years, which is 2 doubling periods, hence the salary will be of:
40000 x 2 x 2 = $160,000.

Answer:
11.84% approx.
Step-by-step explanation:
Expected return = Respective return × Respective probabilities
= (18.5 × 0.71) + (-7.6 × 0.29)
= 10.931%
Probability Return Probability ×(Return - expected return)²
0.71 18.5 0.71×(18.5 - 10.931)² = 40.67573
0.29 -7.6 0.29×(-7.6 - 10.931)² = 99.585409
Total = 140.261139%
=
= 11.84319 ≈ 11.84% approx.
