Tickets to a newly released movie cost $12 but senior citizen tickets cost $6. A total of 20 tickets were sold and $192 was collected in ticket sales. How many tickets, of each kind, were sold?

8 senior tickets, 12 normal tickets.

Step-by-step explanation:

You can find the answer to this by creating two equations: one for the amount of tickets sold and the other for how much money was collected.

I will represent the variables as A for normal tickets and C for senior tickets.

To solve this, you can solve for one of the variables. I will solve for A in the first equation:

Then, you can substitute the new value of A in the second equation:

Knowing that there were 8 senior tickets sold and 20 tickets sold total, we know that there were 12 normal tickets sold.

step-by-step explanation:

1+1=2

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
