Question

Two student groups went to an amusement park on the same day.

Group 1 bought 9 tickets and received a $120 discount.
Group 2 bought 3 tickets and received a $30 discount.
Both groups spent the same total amount of money on tickets.
The price of each ticket was the same.
What was the cost of each ticket?

Let's assume that the cost of each ticket is "x".

For Group 1, the cost of 9 tickets without the discount would be 9x. Since they received a $120 discount, the total amount they spent on tickets is 9x - $120.

For Group 2, the cost of 3 tickets without the discount would be 3x. Since they received a $30 discount, the total amount they spent on tickets is 3x - $30.

Since both groups spent the same total amount of money on tickets, we can set up the following equation:

9x - $120 = 3x - $30

Simplifying the equation, we get:

6x = $90

Dividing both sides by 6, we get:

x = $15

Therefore, the cost of each ticket is $15. Answer: $\boxed{15}$.

To find the cost of each ticket, we need to determine the total amount spent by each group.

Let's assume the cost of each ticket is "x" dollars.

For Group 1:
Number of tickets = 9
Discount received = $120
Total amount spent = (Number of tickets * Cost of each ticket) - Discount
= (9 * x) - $120

For Group 2:
Number of tickets = 3
Discount received = $30
Total amount spent = (Number of tickets * Cost of each ticket) - Discount
= (3 * x) - $30

Since both groups spent the same total amount on tickets:
(9 * x) - $120 = (3 * x) - $30

Simplifying the equation:
9x - 120 = 3x - 30

Bringing the "x" terms to one side:
9x - 3x = -30 + 120
6x = 90

Dividing by 6:
x = 90 / 6
x = 15

Therefore, the cost of each ticket is $15.

So, the correct answer is Option C) $15.

Answer 3

To find the cost of each ticket, let's set up equations for both groups:

Let's assume the cost of each ticket is x dollars.

For Group 1:
Total cost of tickets = Number of tickets × Cost per ticket
9x = Total cost of tickets for Group 1

For Group 2:
Total cost of tickets = Number of tickets × Cost per ticket
3x = Total cost of tickets for Group 2

We are given that both groups spent the same total amount of money on tickets, so we can set up an equation based on that:
Total cost of tickets for Group 1 = Total cost of tickets for Group 2

9x = 3x

To find x, let's subtract 3x from both sides of the equation:
9x - 3x = 0
6x = 0

Divide both sides of the equation by 6 to solve for x:
x = 0 / 6
x = 0

Oops! It seems we made an error in the calculation. Let's go back and try again:

9x - 120 = 3x - 30

Let's subtract 3x from both sides of the equation:
9x - 3x - 120 = 3x - 3x - 30
6x - 120 = -30

Next, let's add 120 to both sides of the equation:
6x - 120 + 120 = -30 + 120
6x = 90

Finally, let's divide both sides of the equation by 6 to solve for x:
x = 90 / 6
x = $15

Therefore, the cost of each ticket is $15.

The correct answer is $15.
