Courtney has a cookie-baking business, and is baking 250 cookies to sell at a weekend festival. The cookies will be sold for $1.50 each. Courtney's total weekend profit can be represented by the function P(c) = 1.50c, where c is the number of cookies sold. What is the domain of P(c)?

• all non-negative multiples of 1.50

• all non-negative number including zero

• all non-negative integers less than or equal to 250

• all non-negative integers and zero

Which points are on the graph of 3x + 3y + 5 = 11?

The admission fee at the fair is $1.50 for children and $4 for adults. On a certain day, 2,200 people entered the fair, and $5,050 was collected. There were 1500 children and 700 adults who attended the fair.

Using the information from Part A, consider the following:

They only sold 80% of the children's tickets and 50% of the adult tickets they had printed. How many total tickets did they have printed?
