Amovie took in $20520by selling a total of 2460tickets. some at $9 and the rest at $7. how many was sold at each price?

Step-by-step explanation:

It usually works well to let the variable represent the quantity of the highest contributor to the mix. Here, we can let x be the number of $9 tickets. Then the total revenue is ...

  $7(2460 -x) +$9(x) = $20520

  2x = 3300 . . . . . . . . . . . . . . . . . . . subtract 17220 and collect terms

  x = 1650 . . . . divide by 2 . . . (number of $9 tickets)

  2460-x = 810 . . . (number of $7 tickets)

1650 tickets were sold at $9, and 810 tickets were sold at $7.

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
