D. Directions: Solve the following grocery problem. Catherine needs some ingredients for her cake. She bought 3 dozen eggs
at $2 each, 2 bags of flour at $4 each, and 1 jug of milk at $3. How much
would it cost Catherine for her ingredients? Show your work.

17$

Step-by-step explanation:

(3 * 2)+ (2 * 4) + (1*3) = 17$

look a the sides they are perpendicular

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:
