X = - 1/3 or an alternate form x = -0.3, x = -3 to the power of -1
Answer:
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

Answer:
#4
Step-by-step explanation:
The function 
represents the profit.
The 1.50 part is the price of each candy bar
The 25 part is the fixed cost incurred
This month, the price of candy bars increased by 0.25, so the "1.50" portion would be increased, NOT "25" portion [fixed cost remained same].
Thus, 1.50 would be increased by 0.25, that is:
1.50 + 0.25 = 1.75
Thus, the new profit function would be:
Answer choice #4 is right.
