Question

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

Answer 1

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

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
