Answer:

Let x be the number of tickets Jake sold,

Since, Sara sells half as many tickets as Jake.

⇒ The ticket sold by Sara =
(x)/(2)

Also, Cole sells 6 more than twice as much as Jake.

⇒ The ticket sold by Cole = 2x + 6,

Thus, the ticket sold by all three =
x+(x)/(2)+2x+6

a) According to the question,


x+(x)/(2)+2x+6=538

b) By solving this equation,


(2x+x+4x+12)/(2)=538


(7x+12)/(2)=538


7x+12=1076


7x=1064


\implies x=(1064)/(7)=152

Thus, the number of tickets Sara has =
(x)/(2)=(152)/(2)=76

We let x be the number of tickets that Sara and Jake sold individually. With this representation, the number of tickets sold by Cole is equal to 2x+6.

(a) x + x + (2x + 6) = 538
The value of x from the generated equation is 133.

(b) Sara sold a total of 133 tickets.
