Question

You earn $84 for mowing 7 lawns. How much do you earn for mowing 4 lawns? un

Answer 1

We have the following:

We can solve by means of a proportion, as follows

`(86)/(7)=(x)/(4)`

solving for x

`\begin{gathered} (86)/(7)=(x)/(4)\rightarrow(x)/(4)=(86)/(7)\rightarrow(x)/(4)\cdot4=(86)/(7)\cdot4 \\ x=(86)/(7)\cdot4 \\ x=(344)/(7)=49.1 \end{gathered}`

Therefore, you would earn a total of $ 49.1
