Hi @ZachKetchup - do you know how to start this equation?

anonymous · Answer

I have no clue how exactly you start it , care to help ?

anonymous · Answer

of course! so, a=640s, and you know what 's' is right?

anonymous · Answer

s goes to 7.5 ?

anonymous · Answer

yes! so, just put 7.5 into your original equation, like so:
$$a = 640*7.5$$

anonymous · Answer

Then you multiply ?

anonymous · Answer

And get 4800 acres ?
