Question

If three pounds of coffee costs $22.56, what is the cost of 1 pound?

Answer 1

We are given the cost of three pounds of coffee, and we are asked to find the cost of one pound. To do that we can use a rule of three, like this:

`\begin{gathered} 3\text{ pounds}\rightarrow22.56 \\ 1\text{pound}\rightarrow x \end{gathered}`

Now we solve for "x" multipliying in cross, like this:

`x=((1pound)(22.56))/(3pounds)`

Now we solve the operations:

`x=7.52`

Therefore, one pound of coffee is $7.52
