EDIT: My brother posted this for me, and wasn't really specific. Just to re-phrase it:

 

 

 

I need the cheapest way to get cannon balls. Experience does NOT matter. I have 3 options and i want to know what is cheapest.

 

1.)Buy the c balls

 

2.)Buy the steel bars and smelt into c balls

 

3.)Buy the ore and smelt it into steel bars and smelt the bars into c balls.

 

 

 

I will NOT be buying the ore, and as previously stated, xp is NOT needed.

 

 

 

Thanks.

Just buy them.. it would be wiser to make money with a skill such as runecrafting.

This is something you can easily figure out on your own.

 

I'll make this easy for you.

 

 

 

Price of cannonballs: http://itemdb-rs.runescape.com/viewitem.ws?obj=2

 

Cost of steel bars: http://itemdb-rs.runescape.com/viewitem.ws?obj=2353

 

Cost of iron ore: http://itemdb-rs.runescape.com/viewitem.ws?obj=2353

 

Cost of coal: http://itemdb-rs.runescape.com/viewitem.ws?obj=453

 

 

 

You get 4 cannonballs per steel bar, and it takes 1 iron and 2 coal to make a steel bar. Now, go do the math on that.

 

(I'm using G.E. links in case the price changes on me, and so he knows where to go.)

Cheapest would be mining the ore, smelting the ore into bars then making cannonballs, most expensive way would be buying cannonballs.

 

 

 

What do you mean by 'best way?' - most efficient, or cost/time effective?

 

 

 

Basically the more you do yourself, the less money you lose.

Cheapest way is buying the cannonballs.

 

This is speaking oppurtunity cost-wise.
