Answer:

  91 child tickets were sold

Step-by-step explanation:

Let c represent the number of child tickets sold. Then the number of adult tickets sold is (150-c) and the total revenue is ...

  5.20c +8.70(150-c) = 986.50

  -3.50c +1305 = 986.50 . . . . simplify

  -3.50c = -318.50 . . . . . subtract 1305

  c = -381.50/-3.50 = 91

The number of child tickets sold that day was 91.

adell [148]

Answer:

$14.56

Step-by-step explanation:

<u><em>Steps to answering this question </em></u>

  1. Determine the total number of comics bought. This can be done by dividing the total amount spent on comics by the unit price of a comic
  2. Determine the selling price of the comic
  3. multiply the amount of comics bought by the selling price

the total number of comics bought = total amount spent on comics / per unit price of comics

$20.16 / $0.72 = 28

selling price = 0.72 - $0.20 = $0.52

Total amount received = selling price x total comics bought

$0.52 x 28 = $14.56
