Work Step by Step

Create a proportion using ratios of bu : acre. $\frac{42000\ bu}{350\ acre}=\frac{x\ bu}{560\ acre}$ Set the product of the means equal to the product of the extremes and solve for the variable. $350\times x = 42000\times560$ $350x=23,520,000$ $350x\div350=23,520,000\div350$ $x=67200$
