Answer
825 lb
Work Step by Step
Create a proportion using ratios of pounds : acre.
$\frac{150\ lb}{40\ acre}=\frac{x\ lb}{220\ acre}$
Set the product of the means equal to the product of the extremes and solve for the variable.
$40\times x = 150\times220$
$40x=33000$
$40x\div40=33000\div40$
$x=825$
