Question

Suppose It takes 6.4 pounds of seed to completely plant one acre of land. Joe has 18.5 acres of land. Find the amount of seed he needs.

Answer 1

`\begin{array}{ccll} lbs&acre\\ \cline{1-2} 6.4&1\\ x&18.5 \end{array}\implies \cfrac{6.4}{x}=\cfrac{1}{18.5}\implies (6.4)(18.5)=x\implies 118.4=x`
