Alan is putting weed killer on a field to get it ready for planting. The directions on the can say to use 4/5 of a quart for each acre of land. How much weed killer will Alan need for two fields, one that is 22 1/2 acres and one that is 38 1/4 acres?
28 1/8 quarts
47 4/5 quarts
60 3/4 quarts
48 3/5 quarts
Sum the total acreage, and multiply by the amount per acre. [tex](22\frac{1}{2} + 38\frac{1}{4}) *\frac{4}{5}[/tex]. Simplified, this is 48.6, or [tex]48\frac{3}{5}[/tex]
