At a sandwich shop there are different kinds of chips . there are 12 bags of potato chips . there are 9 bags of veggies chips . there are 9 bags of corn chips what is the reduced ratio of bags of corn chips total bags of corn chips to total bags of chips?

total bags of chips = (12+9+9) =30

corn : total

9:30

divide by 3 on each side

3:10

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:

1. minimum

2. 6400

3. eight

hope this !
