Grace and her dad are planning to attend the state fair. an adult ticket is $15.00. the price of an adult ticket is one half the price of a student ticket plus $8.00. write an equation to determine how much grace will pay for a student ticket.
a: 1/2x + 8 = 15
b: 1/2x − 8 = 15
c: 1/2x + 15 = 8
d: 1/2x − 15 = 8

The equation is 1/2 x + 8 = 15 ⇒ answer A

Step-by-step explanation:

* Lets explain how to solve the question

- Grace and her dad are planning to attend the state fair

- The price of an adult ticket is $15

- The price of the adult ticket is one half the price of the student ticket

  plus $8

- Assume that the price of the student ticket is x

∵ The price of the student ticket is x

∵ The price of the adult ticket is half the price of the student ticket

   x plus 8

- lets multiply half by x and then add the result by 8

∴ The price of the adult ticket = 1/2 x + 8

∵ The price of the adult ticket is $15

- Equate the expression of the price of the adult ticket by the price of

 the adult ticket

∴ 1/2 x + 8 = 15

* The equation to determine how much Grace will pay for a student

  ticket is 1/2 x + 8 = 15

∴ The answer is choice A

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
