Answer:
![a_n=-12-4(n-1)](https://tex.z-dn.net/?f=a_n%3D-12-4%28n-1%29)
Step-by-step explanation:
The given sequence is
-12,-16,-20...
The first term of this sequence is
.
The common difference is
![d=-16--12](https://tex.z-dn.net/?f=d%3D-16--12)
![d=-16+12=-4](https://tex.z-dn.net/?f=d%3D-16%2B12%3D-4)
The nth term of this arithmetic sequence is;
![a_n=a_1+d(n-1)](https://tex.z-dn.net/?f=a_n%3Da_1%2Bd%28n-1%29)
We substitute the values for the first term and the common difference to obtain;
![a_n=-12-4(n-1)](https://tex.z-dn.net/?f=a_n%3D-12-4%28n-1%29)
Answer:
$ 200.205
Step-by-step explanation:
For the first 10 1/2 hours, she earns $9.50 × 10 1/2 = $99.75
To get the no of hours she worked after that: 20 1/4 - 10 1/2 = 9 3/4 hrs
In 9 3/4 hrs, she earns $10.30 × 9 3/4 = $ 100.425
Total amount of money earned = $99.75 + $ 100.425 = $ 200.205
-779 should be the answer
