Question

Suppose that there are two types of tickets to a show: advance and same day. Advance tickets cost $40 and same day tickets cost $35. For one performance, there were 45 tickets sold in all, and a total amount paid for them was $1700. How many tickets of each type were sold?

Answer 1

25 advance

20 same day

Explanation:

1700=40x+35y

*40 45=x+y

1700=40x+35y

- 1800=40x+40y

-100= -5y

y=20 tickets

45-20=25

25*40 + 35*20= 1700

1000. + 700 = 1700
