Answer:
The number of commercials is 340 and the number of movies are 334.
Step-by-step explanation:
Let the number of commercials be = C
number of movies be = M
According to given conditions:
C = 6 + M --------- eq1
C + M + 6 = $680 ------ eq2
Putting eq1 in eq2:
6 + M + 6 + M = $680
12 + 2M = $680
Subtracting 12 from both sides:
2M = $680 - 12
2M = 668
Dividing both sides by 2:
M = 668/2
M = 334
For finding number of movies put value of M in eq 1
C = 334 + 6
C = 340
So The number of commercials is 340 and the number of movies are 334.

X^2 - 10x + 8 =0
x^2 - 10 + (-10/2)^2 - (-10/2)^2 + 8 = 0
(x - 5)^2 - 25 + 8 = 0
(x - 5)^2 - 17 = 0
To be honest , this is the final step for this equation. It seems like there is no any suitable answer for this question..
To me , I think the best answer will be the third option.
x - 5 =0
x = 5
2x-10 = 0
2x = 10
x = 5
I guess this answer seems like legit.. So I will choose the third option.
