A man divides 3 hectares of land evenly among his 8 sons. If every 750m^2 of this land can be used to make a profit of $500 from every 3 months of commercial farming, how much can each son make if they cultivate their share of the land for one year(1 hectare is equal to 10000 m^2)?
There are 10000m^2 in each hectare, so 3 hectares contains 3*10000 = 30000m^2 of land
30000m^2 is divided among 8 sons so each son will get 30000/8 = 
<gadget id="calculator">30000/8</gadget>
<output>3_750</output>
3750m^2.
In every 3750m^2, there are 3750/750 = 
<gadget id="calculator">3750/750</gadget>
<output>5</output>
5 portions of 750m^2 areas of land.
Each son can make 5*$500 = $
<gadget id="calculator">5*500</gadget>
<output>2_500</output>
2500 every 3 months from cultivating their share.
In one year there are 12 months so each son can make $2500 up to 12/3 = 
<gadget id="calculator">12/3</gadget>
<output>4</output>
4 times in a year.
Each son can make a total of $2500*4 = $
<gadget id="calculator">2500*4</gadget>
<output>10_000</output>
10000 in a year.
