Given -
The combined cost of one advance ticket and one same-day ticket = $70
40 advance tickets and 30 same-day tickets were sold and the totaliamo nt for th etickets was = $2400
To Find -
The price of each kind of ticket =?
Step-by-Step Explanation -
Let the cost of an advanced ticket = A
and a same-day ticket = S
Now, According to the question,
A + S = $70 .......(1)
Also,
40A + 30S = $2400
30(A+S) + 10A = $2400
Now, Putting the value from 1 in above =
30(70) + 10A = 2400
10A = 2400 - 2100
10A = 300
A = 30
So,
S = 70 - 30 = 40
Final Answer -
Advance ticket = $30
Same-day ticket = $40
