Movie Galore Video Store is open every day of the year. To rent movies from the store, a person has to pay an annual membership fee of $20, plus $2.50 for each movie rented. To reduce the chance that movies are returned late, members are not allowed to rent more than 10 movies per day. Billy decides to become a member of the video store. Let x represent the number of movies that Billy could rent next year, and let f (x) represent the amount (in dollars) that he would pay the store as a result. Then f (x) is a function of x. What is the domain D and range R of f (x)?

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

hi how are you doing today, if you need just ask me.

step-by-step explanation:

17
