) - At a farming supply store 7 pounds of seed cost $141.96. If a farmer needed 4 pounds ofseeds, how much would it cost him?

Answer 1

Hello

From the question, we know that 7 pounds of the seeds cost $141.96.

4 pounds would be assumed to be x and we can solve for x.

`\begin{gathered} 7\text{ pounds = 141.96} \\ 4\text{ pounds = x} \end{gathered}`

Cross multiply both sides.

`\begin{gathered} 7* x=4*141.96 \\ 7x=567.84 \end{gathered}`

Divide both sides by the coefficient of x

`\begin{gathered} 7x=567.84 \\ (7x)/(7)=(567.84)/(7) \\ x=81.12 \end{gathered}`

From the calculation above, the cost of 4 pounds of the seeds is equal to $81.12
