Answer:
To reach this sales value by producing more child tickets than adult tickets, it will be necessary to sell 90 child tickets and 60 adult tickets.
Step-by-step explanation:
In order for the sale of 150 tickets to give a value equal to 102 dollars, and the child tickets were sold in greater quantity than the adult tickets, we would need to sell 90 child tickets and 60 adult tickets. This can be confirmed by calculating:
60 * 0.8 = 48 dollars.
48 + (90 * 0.6) = 102 dollars.
