A grocery stores with a bag of six oranges for $4.20 in and spends $ 2.80and oranges how many did he buy?

He buys 4 oranges

Step-by-step explanation:

in order to solve this equation you have to find the price of only one orange so we are going to have to divide $4.20 by 6:

$4.20/6 = 0.7

So for every orange he spends $.70, so now we're going to divide 2.80 by $.70 so we can get the number of oranges bought:

2.80/ 0.70 = 4

So he bought 4 oranges.

I hope this helps you
