3. A worker within the middle income class is preparing to retire. In the year before he retired, his gross monthly earnings are $2,000. His Social Security benefits will be $1,200 per month. Before he retired, his income was subject to a tax of 25 percent. Find his before-tax and after-tax replacement rates

The replacement rate is the percentage of the final income that the pension compensates.

Before-tax replacement rate:

The worker made $2,000, and his social security benefits are $1,200.

1,200 x 100% / 2,000 = 60%

The before-tax replacement rate is 60%.

After-tax replacement rate:

His 2,000 income was subject to a 25% tax.

2,000 x 25% = 500

His after-tax income was 1,500

1,200 x 100% / 1,500 = 80%

The after-tax replacement rate is 80%.

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
