Pamela is selling cookies. She charges 75 cents for each cookie, with the ingredients costing $2.00 per dozen. The cookies are only sold by the dozen. Her profit is represented by the equation P = 7d. What does the domain of the function represent? Which values in the domain are relevant to the amount of profit?

Respuesta :

Answer:

  • 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

Answer:

Number of dozen cookies sold- d > or equal to 1
