It would be 40% because those percentages added up would be 90

Answer: Choice A</h3><h3>
9.80h+10 = 88.40</h3>
===========================================================
Work Shown:
- h = number of hours worked.
- 9.80h = amount of money earned after working h number of hours (ignoring the meal bonus).
- 9.80h+10 = total amount of money earned after adding on the meal bonus.
- 9.80h+10 = 88.40 is the equation we use since the total 9.80h+10 is the same as the total she earned 88.40 dollars.
--------------------
Extra info (optional section)
If you want to solve for h, then you could follow these steps.
9.80h+10 = 88.40
9.80h = 88.40-10 ... subtract 10 from both sides
9.80h = 78.40
h = 78.40/9.80 .... divide both sides by 9.80
h = 8
Valerie worked 8 hours on Friday.
As a check,
9.80h + 10 = 88.40
9.80*8 + 10 = 88.40
78.40 + 10 = 88.40
88.40 = 88.40
The answer is confirmed.
The additive comparison is talking about adding and multiplicative comparison is talking about multiplication but the difference is the comparison.
