Answer:
The answer is D) $13.50
Step-by-step explanation:
So first what you're gonna do it subtract $9.50 from $36.50 which will get you to $27.00.
Then you'll have to figure out what half of $27.00 is.
That will get you to the answer of D) $13.50
x = 0
a=6 or -6
Solve the determinant to get a²-36=0
(a-6)(a+6)=0
Answer: $5.25
25/100 = 0.25
0.25 * 7 = 1.75
7 - 1.75 = 5.25
