It snowed 8 feet of snow in 30 1/2 hours. How much did it snow in 1 hour? Show all work.

approx 1/4 inch of snow in 1 hour

Step-by-step explanation:

set up a proportion and cross-multiply:

8 / 30.5 = x / 1

30.5x = 8

x = 8/30.5

x = 0.26

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:
