Answer:
Dwayne worked 20 hours for first job and 25 hours for second job.
Step-by-step explanation:
Let the number of hours worked by Dwayne in first job = x
Let the number of hours worked by Dwayne in second job = y
Then,
----------------- (1)
First job pays $14 per hour
Second job pays $10 per hour
=>
------------- (2)
Solving (1) and (2):
![\[y = 45 - x\]](https://tex.z-dn.net/?f=%5C%5By%20%3D%2045%20-%20x%5C%5D)
Substituting in (2):
![\[14x + 10 (45-x) = 530\]](https://tex.z-dn.net/?f=%5C%5B14x%20%2B%2010%20%2845-x%29%20%3D%20530%5C%5D)
=> ![\[14x + 450- 10x = 530\]](https://tex.z-dn.net/?f=%5C%5B14x%20%2B%20450-%2010x%20%3D%20530%5C%5D)
=> ![\[4x = 530 - 450\]](https://tex.z-dn.net/?f=%5C%5B4x%20%20%3D%20530%20-%20450%5C%5D)
=> ![\[4x = 80\]](https://tex.z-dn.net/?f=%5C%5B4x%20%20%3D%2080%5C%5D)
=> ![\[x = 20\]](https://tex.z-dn.net/?f=%5C%5Bx%20%20%3D%2020%5C%5D)
Substituting in (1):
![\[y = 45 - x\]](https://tex.z-dn.net/?f=%5C%5By%20%3D%2045%20-%20x%5C%5D)
=> ![\[y = 45 - 20\]](https://tex.z-dn.net/?f=%5C%5By%20%3D%2045%20-%2020%5C%5D)
=> ![\[y = 25 \]](https://tex.z-dn.net/?f=%5C%5By%20%3D%2025%20%5C%5D)
This sequence can be defined as: 3n+1
So, if you plugged in 50 for n, you would get-
(3×50)+1
so the answer is 151
