A. 1,180,000
B. 1,200,000
C. 1,200,300
D. 1,228,500
E. 1,330,000

Say at the beginning of 1992, Maria's portfolio was worth $100. I assumed this value as this would make things easier for computation. Later, I will multiply the result by 6,000 to get the final answer.

Portfolio's value at the end of 1992 = 100 + 100*95% = 195
Portfolio increased in value during 1993 = 195*5% = 9.70

Portfolio's value at the end of 1993 = 195 + 9.70 = appx 205

Thus, the portfolio's value at the end of 1993 = appx 205 * 6,000 = $1,230,000

The closest answer is Option D.

The correct answer: D

Hope this helps!
