Answer:

Price of advance ticket: 15$

Price of same-day ticket: $40

Step-by-step explanation:

Let y be the price of one advance ticket and x the cost of one same day ticket.  

We know that the combined cost of one advance ticket and one same-day ticket is $55, so

y+x=55 equation (1)

We also know that 20 advance tickets and 35 same-day tickets cost $1700, so

20y+35x=1700 equation (2)

Now, let's solve our system of equations step-by-step:

step 1. Solve for x in equation (1)

y+x=55

x=55-y equation (3)

step 2. Replace equation (3) in equation (2)

20y+35x=1700

20y+35(55-y)=1700

20y+1925-35y=1700

-15y=-225

y=\frac{-255}{-15}

y=15 equation (4)

step 3. Replace equation (4) in equation (3)

x=55-y

x=55-15

x=40

We can conclude that the price of one advance ticket is $15 and the price of one same-day ticket is $40.
