How many quarts are in 3 3/4 % of 20 gallons?

3 qt

Step-by-step explanation:

First, let's convert 20 gallons into quarts.

20 gal * (4 qt)/(gal) = 80 qt

3 3/4% of 80 qt =

= 3.75% * 80 qt

= 0.0375 * 80 qt

= 3 qt

repeat the question

step-by-step explanation:

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:
