A company sells cupcakes for $4.25 each. If the variable costs are $1.95, what is the contribution margin

Contribution margin per unit = $2.3

Explanation:

The contribution margin per unit is the contribution or amount provided by the sale of each unit towards covering the fixed costs of the business. The contribution margin per unit is calculated by subtracting the unit variable costs by the sales revenue per unit.

Contribution margin per unit =  Sales revenue per unit - Variable cost per unit

Contribution margin per unit = 4.25 - 1.95

Contribution margin per unit = $2.3

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.
