Hello Amie,

You should start by setting up equations using what you know.

Here is an equation for how much Fionas is paid per hour when she does not exceed 37.5 hours y= 21.50x. Let y= the amount she is paid and x= the number of hours she work that are equal to or less than 37.5.

When she works over 37.5 hours, "she is paid 1.5 times the regular rate of $21.50". That is she is paid (21.50 x 1.5= 32.25 each hour over 37.5). So y= 21.50x +32.25z. Let z= the number of hours over 37.5.

The problem says that she worked 5, 0, 7, 7, 5, 8.5, 8 and 7 hours. That is a total of 47.5. This is over 37.5 hours, but by how many hours? To figure this out, do 47.5-37.5= 10. So, let z=10 and x=37.5. Plug this into the equation we formulated.

y=21.50x +32.25z

y=21.50 (37.5) + 32.35 (10)

y= 806.25 + 323.50

y= 1129.75

Fionas gross earning for the week was $1,129.75.

I hope this helps. If you need any clarifications,let me know.

It appears that this gives Fiona 8 days of the week to work lol. Its possible that one of the numbers doesn't belong?

So the first thing to do is to calculate how many hours Fiona worked (5+0+7+7+5+8.5+8+7). If this exceeds 37.5, then you need to know how many hours she went over because the first 37.5 hours gets $21.50, and the remainder receives (1.5 x $21.50). The set-up should look something like this:

(37.5 x 21.50) +((5+0+7+7+5+8.5+8+7) x (1.5 x $21.50))

Does that make sense?
