Based on the available information, the Grace will pay $14 for the student ticket.
Let x be the price of a student ticket.
The price of an adult ticket is given as $15, and it is also stated that the price of an adult ticket is half the price of a student ticket plus $8. Therefore, the equation representing this relationship is:
15 = 1/2x + 8
To determine how much Grace will pay for the student ticket (x), you can solve this equation for x:
1/2x = 15 - 8
1/2x = 7
Now, multiply both sides by 2 to isolate x:
x = 2 * 7
x = 14
So, the equation to determine how much Grace will pay for the student ticket is x = 14.
Therefore, Grace will pay $14 for the student ticket.
