In a cinema hall a total of 215 tickets were sold. Some were sold at $8 and others at $12. If the total amount collected was 2180, how many $8 tickets were sold​

100 tickets.

Step-by-step explanation:

Number of $8 tickets sold = xNumber of $12 tickets sold = y

Set up two equations: one representing total amount sold and another representing total dollars earned.

Rearrange x + y = 215 and find the value of x:

Substitute it into the other equation and solve for y:

Substitute in the y-value to the other expression to find x:

Therefore, they sold 100 of the $8 tickets.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good

Iagree that is the answer to the question
