Digby has a roe of 0.24 (roe = net income/equity). that means:

each dollar that is invested by the shareholders

Explanation:

The formula to compute the return on equity is shown below:

Return on equity = (Net income) ÷ (total equity)

It shows a relationship between the net income and the total equity so that the correct percentage can be computed.  

It also shows the profitability of the company which reflects each dollar that is invested by the shareholders

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.
