Question

Amanda made $161 for 7 hours of work. At the same rate, how many hours would she have to work to make $229?

Answer 1

I got 13 hours but I'm not sure if my method is what my teacher is looking for.. I don't know what equation would solve this.

Answer 2

The first step is to find how much she earns for each hour of work:
\[\large Hourly\ rate=\frac{161}{7}=23\]
So, she earns $23 per hour. Therefore is she worked for 10 hours she would earn 23 * 10 = $230.
Therefore to earn exactly $229 she must work slightly less than 10 hours:
\[\large \frac{229}{23}=9.96\ hours\]
