The play took in $728 one night. the number of $8 adult tickets was 14 less than twice the number of $5 child tickets. how many of each ticket were sold

Step-by-step explanation:

Let c represent the number of child tickets sold. Then 2c-14 is the number of adult tickets sold, and total revenue is ...

  5c +8(2c-14) = 728

  21c -112 = 728 . . . . . . simplify

  21c = 840 . . . . . . . . . . add 112

  c = 40 . . . . . . . . . . . . . divide by 21

  2c-14 = 66 . . . . . . . . . number of adult tickets sold

66 adult tickets and 40 child tickets were sold.
