Question

David made $168 for 12 hours of work. At the same rate, how many hours would he have to work to make $238

Answer 1

Given:

For 12 hours of work, david made $168.

To find the required time to make $238.

Since, it is in direct proportion.

We can write it as,

`\begin{gathered} 12\colon168\Colon x\colon238 \\ x*168=12*238 \\ x=(12*238)/(168) \\ x=17 \end{gathered}`

Hence, the required time to make $238 is 17 hours.
