A grocery store sells a bag of 6 oranges for $4.20. If Ayden spent $2.80 on oranges, how many did he buy?

4 bags of oranges

Step-by-step explanation:

First, we need to find out how much each bag of oranges costs so we divide.  

$4.20 divided by 6 equals 0.7 which means that each bag of oranges costs $0.70.

Next we need to find out how much Ayden spent on oranges so we divide 0.70 by 2.80

2.80 divided by 0.70 equals 4.

This means that Ayden bought 4 bags of oranges.

Hope this helps!

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:
