Tickets to a band concert were $5.00 for balcony and $10.00 for orchestra seats. if attendance at one show was 800, and if the total receipts for that show for $if attendance at one show was 800, and if the total receipts for that show $7000, how many people bought orchestra seats?

600

Step-by-step explanation:

concert=x

orchestra= 800-x

5x+10(800-x)=7000

5x+8000-10x=7000

-5x=-1000

x=200

800-x=600

Check

200*5=1000

600*10=6000

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
