A.5, 185
B.370, 230
C.410, 90
D.480, 20
E.250, 250
for this question you need to form two equation and do simultaneous equation. first you need to let A tickets to be x and B tickets to be y. the first equation is 10x+60y=6000 the second equation is x+y=500 use one of the equation and make the one expression the subject. so i choose equation two. x+y=500 x=500-y (equation 3) sub equation 3 into equation 1,
