A small company has the marketing information that 35 units will sell daily at a price of $34.75 per unit, and that sales will rise to 36 units per day at a price of $33.06 per unit. Use this information to create a linear demand function, then create the associated revenue function and find the price that will yield the maximum revenue.

comment it always confuses me

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.
