The equation t = 10.5(c + a) represents the total money earned by the company from the sale of tickets
<u>Solution:</u>
Given that,
Ticket charged for people of all age groups = $ 10.50 per ticket
Let "c" represents the total number of children who bought tickets
Let "a" represents the total number of adults who bought tickets
Now, let the total money collect be represented by "t"
Number of people bought tickets = number of children bought tickets + number of adults bought tickets
<em><u>Now the total money earned by company is given as:</u></em>
Total money earned = cost per ticket x number of people bought tickets
Total money collected = cost per ticket x (number of children bought tickets + number of adults bought tickets)
Substituting the known values we get,
t = 10.5(c + a)
Hence, the required equation is t = 10.5(c + a)
