Answer:
B. $1,500.
Step-by-step explanation:
We have been given that Rob Retiree gets a Social Security benefit of $800 per month. His wife receives a benefit equal to 50 percent of Rob's benefit.
Let us find out amount of benefit received by Rob's wife by finding 50% of $800.
[tex]\text{Benefit received by Rob's wife}=\frac{50}{100}\times\$800[/tex]
[tex]\text{Benefit received by Rob's wife}=0.50\times \$800[/tex]
[tex]\text{Benefit received by Rob's wife}=\$400[/tex]
As they take an additional $300 per month from savings, so to find their monthly income we will add Rob and his wife's benefits to monthly savings.
[tex]\text{Total monthly income}=\$800+\$400+\$300[/tex]
[tex]\text{Total monthly income}=\$1500[/tex]
Therefore, their total monthly income is $1500 and option B is the correct choice.
