B=number of ticets sold before

a=number of tickets sold after

cost of a ticket=number of tickets times cost per ticket

beforecost=39.95b

aftercost=54.95a

total cost=925000

39.95b+54.95a=925000

total number tickets=20000

b+a=20000

we have

39.95b+54.95a=925000

b+a=20000

multiply second equation by - 39.95 and add to first equatin

39.95b+54.95a=925000

-39.95b-39.95a=-799000 +

0b+15a=126000

15a=126000

divide bot sides by 15

a=8400

sub back

b+a=20000

b+8400=20000

minus 8400 both sides

b=11600

11,600 tickets sold before

8400 tickets sold after
