Question

If 5 lb of oranges cost $11.55 how many would it cost for 12 lb of oranges

Answer 1

To solve this problem we can apply the rule of three, in our case

`\begin{gathered} 5\rightarrow11.55 \\ 12\rightarrow x \end{gathered}`

Then, 12 lb of oranges will cost

`((12)(11.55))/(5)=(138.6)/(5)=27.72.`

Therefore, 12 lb of orange will cost $27.72.
