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.
Answer:
The percent attendance for that semester was 30%.
Step-by-step explanation:
In this problem, out of 190 students, only 57 students had perfect attendance. When a question says something like this, then it means that you are going to use division. You are going to divide 57 by 190.
57 ÷ 190 = 0.3
Now, multiply 0.3 by 100 to get the percentage.
0.3 * 100 = 30
So, the percentage of the perfect attendance is 30%.
