Hi so I’m going to help you answer this problem so let’s get started!
What you need to do is 7+0.2(7)=7+1.40=8.40
Now that you know that James makes 7 dollars per hour and Priya makes 20% more than this, what you need to do is find 20% of 7% which you need to do is use 0.2(7) and then add that to 7 so that you can find the pay per hour for Priya.
8.40-0.05(8.40)=8.40-0.42=7.98
Since Priya made 8.40 dollars per hour and Siobhan made 5% less than this, what you now have to find is 5% of $8.40 which the equation is 0.05($8.40) and then you’ll need to subtract that from $8.40 so that you can find the pay per hour for Siobhan.
Therefore $7.98 is how much Siobhan makes per hour.
