To determine how many boxes of bananas you can buy for $900, you first need to find out the cost of one box of bananas. Since five boxes cost $3000, you can calculate the price per box by dividing the total cost by the number of boxes.
Price per box = Total cost / Number of boxes = $3000 / 5 = $600.
Now that you know each box costs $600, you can find out how many boxes you can buy with $900. This is done by dividing the available amount by the price of one box:
Number of boxes = Amount available / Price per box = $900 / $600 = 1.5.
Since you can’t buy half a box, you can only purchase 1 box of bananas for $900.
