a. $31,000
b. $31,500
c. $32,500
d. $35,000
e. $52,500

Explanation:

Step1: Find the pattern in income increase

Calculate the difference between consecutive incomes:

• \( 21000 - 17500 = 3500 \)
• \( 24500 - 21000 = 3500 \)
• \( 28000 - 24500 = 3500 \)

So, the income increases by $3500 each year.

Step2: Calculate 2008 income

Add the increase to 2007's income:
\( 28000 + 3500 = 31500 \)

Answer:

B. $31,500
