Step-by-step explanation:

DOMAIN-number of dozens(d) of cookie sold.The set of whole numbers/positive integers

Step-by-step explanation:

The function P=7d represents her profit.

Profit = Income - Expenses

The ingredients costs $2.00 per dozen.

She charges 75 cents for each cookie, therefore a dozen is sold at:

$(12 X 0.75)=$9

Profit = Income - Expenses = 9-2 =$7

The domain of the function P=7d  represents the number of dozens(d) of cookie sold.She sells only by the dozen(no half of a dozen) and the minimum amount of dozen which she can sell is 1, therefore the values in the domain which are relevant to the amount of profit are 1,2,3,... The set of whole numbers/positive integers
