Question

Four pounds of flour cost $2.60 how much flour do you get per dollar? round your answer to the nearest hundredth, if necessary.

Answer 1

Since 4 pounds of flour costs $2.60, we have that:

`\begin{gathered} 4\text{pounds}\to2.60 \\ x\to1 \end{gathered}`

Where x is the amount of flour you get for 1 dollar.

We can rewrite the expression above as follows:

`\begin{gathered} \frac{4\text{pounds}}{2.60}=\frac{x\text{ pounds}}{1} \\ \Rightarrow x\text{ pounds}=(4pounds)/(2.6)=1.53846\ldots \\ \Rightarrow x\approx1.54 \end{gathered}`

Then, we get 1.54 pounds of flour per dollar
