Andrew, Chris, Jeremy and Glen sold some funfair tickets. Both Andrew and Glen sold 1/5 of the tickets each. Chris sold 12 tickets more than Andrew and Jeremy sold 30 tickets. How many tickets did they sell altogether?
Call the total sold =T
A = (1/5)T
C = (1/5)T + 12
G = (1/5) T
J = 30
(1/5)T + (1/5)T + 12 + (1/5)T + 30 = T simplify
(3/5)T + 42 = T
42 = T - (3/5)T
42 = (2/5)T
T = 42 ( 5/2) = 105
