Answer:

let the number of door tickets be x

so, eventually the number of advanced tickets will be. x-30

the total cost=2630.

(x-30)3+5x=2630

3x-90+5x=2630

8x-90=2630

8x=2630+90

8x/8=2720/8

x=340

x-30

340-30

310.

total tickets sold=310+340=650

Therefore, the total tickets bought was 650, 310 was advanced and 340 was door tickets

9.4 yards to feet show conversion factors
hammer [34]
There are 3 feet in 1 yard, that is 3ft/1yd or 1yd/3ft

you can use either, now, in this case, we want to convert
from yards to feet, so, that means we want to cancel out
the yards unit, so we use the form with the "yd" at the bottom
of the fraction, so it cancels out with the one above

\bf 9.4\boxed{yd}\cdot \cfrac{3ft}{1\boxed{yd}}\implies \cfrac{9.4\cdot 3ft}{1}\implies 9.4\cdot 3ft

A movie theater charges $11.00 for adults, $6.50 for children, and $9.00 for senior citizens. One day the theater sold 405 ticke
Eva8 [605]

Answer: 110 adult, 220 children and 75 senior citizens went to the theater that day.

Step-by-step explanation:

Let x represent the number of adults that went to the theater that day.

Let y represent the number of children that went to the theater that day.

Let z represent the number of senior citizens that went to the theater that day.

One day the theater sold 405 tickets. This means that

x + y + z = 405 - - - - - - - - - - - -1

movie theater charges $11.00 for adults, $6.50 for children, and $9.00 for senior citizens and the total number of receipts that were collected was $3315. This means that

11x + 6.5y + 9z = 3315 - - - - - - - - - -2

Twice as many children’s tickets were sold as adult tickets. This means that

y = 2x

Substituting y = 2x into equation 1 and equation 2, it becomes

x + 2x + z = 405

3x + z = 405 - - - - - - - - - - - - - 3

11x + 6.5 × 2x + 9z = 3315

11x + 13x + 9z = 3315

24x + 9z = 3315 - - - - - - - - - - -4

Multiplying equation 3 by 9 and equation 4 by 1, it becomes

27x + 9z = 3645

24x + 9z = 3315

Subtracting, it becomes

3x = 330

x = 330/3

x = 110

Substituting x = 110 into equation 3, it becomes

3 × 110 + z = 405

330 + z = 405

z = 405 - 330

z = 75

y = 2x = 2 × 110

y = 220
