You can put this solution on YOUR website!
The units have to make sense in any problem
You are given:
Each pig eats: [ 2.8 pounds of grain / day ]
Cost of grain: [ $7.25 / pound of grain ]
----------------------------------------
[ $7.25 / pound of grain ] x [ 2.8 pounds of grain / day ] = [ cost to feed 1 pig for 1 day ]
+7.25%2A2.8+=+20.3+
This is:
$20.30 / 1 pig / 1 day
+20.3%2A60+=+1218+
The cost is:
$1,218 / 1 pig / 60 days
-------------------------
Note that you get the same result if you
feed 60 pigs for 1 day
----------------------------------------
The conversion to use is:
1 acre = .00156 square miles
In terms of units:
[ number of acres ] x [ square mi / acre ] = [ square mi ]
+2067795%2A.00156+=+3225.76+
3,225.76 square miles
