Adrian is a songwriter who collects royalties on his songs whenever they are played in
a commercial or a movie. Adrian will earn $40 every time one of his songs is played
in a commercial and he will earn $130 every time one of his songs is played in a
movie. Adrian earned a total of $1010 in royalties on 14 commercials and movies.
Write a system of equations that could be used to determine the number of
commercials and the number of movies on which Adrian's songs were played. Define
the variables that you use to write the system.

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:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
