70

80

90

100

Answer 1

i think it was like 80

Answer 2

two ways to solve
you can write
\[x+y=170\] that is, the total of the two types of tickets sold is 170 and
\[2x+3.5y=490\] i.e. the total amount of money was 490 then solve this

Answer 3

i got the answer to be 80

Answer 4

or you can put \(x\) equal the number of $2 tickets so \(170-x\) is the number of $3.50 tickets and solve
\[2x+3.5(170-x)=490\] fpr \(x\)

Answer 5

70
