James, Priya, and Siobhan work in a grocery store. James makes
$8.00
per hour. Priya makes
20%
more than James, and Siobhan makes
15%
less than Priya. How much does Siobhan make per hour?
If Priya makes 20% more than James and Siobhan makes 15% less than Priya, then it follows that Priya makes 85% of 120% of James' hourly wage. Which is to say that Siobhan makes 85% of $9.60 per hour. Since 85% of $9.60 is $8.16, this means that Siobhan makes $8.16 an hour.
