Which type of cost-plus contract provides the seller with a guaranteed dollar-value profit rather than as a percentage

Cost-plus-fixed-fee

Explanation:

A cost-plus contract is a form of contract whereby a contractor will be paid for all of its expenses and an additional payment will also be added in order to give room for a profit.

A cost-plus-fixed-fee contract is a when the payment that will be made to the contractor has been fixed at the start of the contract. In this situation, the fixed fee is not dependent on the actual cost. It provides the seller with a guaranteed dollar-value profit rather than as a percentage.

you had the wrong answer

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.
