Question

Hope works 21.5 hours every week. If she earns $8.50 per hour, how much does she make in 3 weeks?

Answer 1

You can use conversion factors to solve this.

`(21.5hours)/(week) * (8.50dollars)/(hour) * (3 weeks)`

The hours and weeks cancel and you're left with dollars; which makes sense.

`(21.5cancel(hours))/cancel(week) * (8.50dollars)/cancel(hour) * (3 cancel(weeks))=548.25dollars`
