c + 10.5a

21(c + a)

Answer 1

10.5(c+a) represents the total money earned by the company from the sales of tickets.

Step-by-step explanation:

Given,

Charges per ticket = $10.50

Let,

c represents the number of children who bought tickets.

a represents the number of adults who bought tickets.

Therefore,

Total money earned = Charges per ticket*number of children who bought tickets + Charges per ticket*Number of adults who bought tickets

Total money earned = 10.5c + 10.5a

Taking 10.5 common;

Total money earned = 10.5(c+a)

10.5(c+a) represents the total money earned by the company from the sales of tickets.
