recall that betty arranged equal numbers of movies on four shelves of a shelving unit and placed 6 of her favorite movie on the top shelf if x is the number of movies on each shelf, the expression for the total number of movies on the shelving unit is 4x + 6 if each of the 4 shelves holds 14 movies, how many movies does betty have on her shelving unit? show your work

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:
