Answer:
50 hours.
Step-by-step explanation:
First I found how how much the man was paid in a week for the base 40 hours which was 384. Then i subtracted that from the wage from the week so i could just have the overpay amount which was 144. I then multiplied 9.6 by 1.5 to get the hourly pay for overtime and god 14.4 dollars an hour. Lastly, i divided 144 by 14.4 and got 10 extra hours which got me to my answer of 50 hours because i added the 40 initial hours.
Answer:
![\huge\boxed{S_8=3,280}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7BS_8%3D3%2C280%7D)
Step-by-step explanation:
The formula:
![S_n=\dfrac{a_1(1-r^n)}{1-r}](https://tex.z-dn.net/?f=S_n%3D%5Cdfrac%7Ba_1%281-r%5En%29%7D%7B1-r%7D)
Substitute:
![n=8;\ r=3;\ a_1=1\\\\S_8=\dfrac{1\cdot(1-3^8)}{1-3}=\dfrac{1-6,561}{-2}=\dfrac{6,560}{2}=3,280](https://tex.z-dn.net/?f=n%3D8%3B%5C%20r%3D3%3B%5C%20a_1%3D1%5C%5C%5C%5CS_8%3D%5Cdfrac%7B1%5Ccdot%281-3%5E8%29%7D%7B1-3%7D%3D%5Cdfrac%7B1-6%2C561%7D%7B-2%7D%3D%5Cdfrac%7B6%2C560%7D%7B2%7D%3D3%2C280)
Answer: Your answer will be ![\frac{-50}{5} =-10](https://tex.z-dn.net/?f=%5Cfrac%7B-50%7D%7B5%7D%20%3D-10)
Step-by-step explanation: You will have
you will have to multiply 5 on both sides. So you will then simplify 5 and 5 to be left with n and multiply -10(5)=-50
So you get ![n=-50](https://tex.z-dn.net/?f=n%3D-50)
