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?
Question 9 options:
$25
$12.50
$15
$7.50
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.
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.
