3) The school that Jill goes to is selling tickets to a fall musical. On the first day of ticket sales the school sold 3 senior citizen tickets and 6 child tickets for a total of $102. The school took in
$184 on the second day by selling 1 senior citizen ticket and 12 child tickets. Find the price of a
senior citizen ticket and the price of a child ticket.

Step-by-step explanation:

x - number of senior citizen tickets sold

y - number of child tickets sold

1st day: 3x + 6y = 102

2nd day: x + 12y = 184

2 (3x + 6y = 102)

= 6x + 12y = 204

-1 (x + 12y = 184)

= -x - 12y = -184

6x + 12y = 204

-x - 12y = -184

= 5x = 20

x = 4

3(4) + 6y = 102

= 12 + 6y = 102

= 6y = 90

y = 15

One senior ticket is $ 4.00 and one child ticket is $ 15.00

Hope this helps! :D

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: it's a
