$520.96

Step-by-step explanation:

The composite is made up of 2 semicircles and a rectangle:

⇒ Radius of the circle = 2 ft

⇒ Length of the rectangle = 5 ft

⇒ Width of the rectangle = 4 ft

Area

⇒ π(2)² + (5 x 4)

⇒ 4π + 20

⇒ 32.56 ft²

Cost

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:
