The pharmacy has in stock 3 L of the drug solution in the bed veterinarian is needing to quarts how many quarts will be remaining of the 3 L after the solution is made

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:

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

the answer is $23.63
