## Elementary Technical Mathematics

Given airplane sprayer hold 60 gal, $\frac{3}{4}$ gal of water and $\frac{1}{2}$ lb of pesticide is required per acre therefore we need to calculate pesticide powder needed per tankful 60 $\div$ $\frac{3}{4}$ gal = 60 x $\frac{4}{3}$ =80 acre Pesticide required = 80 x $\frac{1}{2}$ lb = 40 lb
