Gab's tickets = G = 65

Pat's tickets = P = x

Joe's tickets = J = y

1) Gab sold 25 less than two times Pat sold: G = 2x - 25 (but G = 65)

2) Pat sold 30 more than Joe: x = y + 30

From equation (1), 65 = 2x - 25 ==> 90 = 2x ==> x = 45

From above and equation (2), 45 = y + 30 ==> y = 15

Gab sold 65, Pat sold 45, and Joe sold 15 so they sold 125 in total.
