50 adults and 40 children attend in the cinema whats the formula

Answer 1

The formula is:

Money Collected = (Number of Adults)(Price of an Adult Ticket) + (Number of Children)(Price of a Child Ticket)

You told us that the Number of Adults = 50 and the Number of Children = 40. So:

Money Collected = (50)(Price of an Adult Ticket) + (40)(Price of a Child Ticket)

You did not tell us the prices for the adult and child tickets, but you can read them from your problem and put them into the formula and compute the answer.
