(a) 4280 = 2300 + 60c, so 60c = 1980, and thus c = 33 copies
(b) 60(21) + 2300 = $3560
From my research, i am pretty sure he will have $1120
HOPE I GET BRAINLIEST PLS
REASONS:-
1ST STEP
![6x + 7 = 8x - 17](https://tex.z-dn.net/?f=6x%20%2B%207%20%3D%208x%20-%2017%20)
GIVEN LHS = RHS
2ND STEP
![7 = 2x - 17](https://tex.z-dn.net/?f=7%20%3D%202x%20-%2017)
Bez +ve 6x when move to another side will change to -ve so it reduces 8x to 2x
3RD STEP
![24 = 2x](https://tex.z-dn.net/?f=24%20%3D%202x%20)
Bez -ve 17 when move to another side will change to +ve so it increases 7 to 24
4TH STEP
![12 = x](https://tex.z-dn.net/?f=12%20%3D%20x)
Bez 2 in multiplication when move to another side will change to division so it reduces 24 to 12
5TH STEP
![x = 12](https://tex.z-dn.net/?f=x%20%3D%2012)
it the answer we obtained after solving
Answer:
X/3 X is unknown, so it would be this until you figure out X
