C. $111.65 would be the answer
Answer:
I got the same question rn
Step-by-step explanation:
What did you end up with for the answer?
I'm taking a guess that regular price would be $1,106.64 plus the 6% tax
The function of the trapezoid area is:
A(x)=(B+b)*h/2
Where B and b are the bases and h is the height.
With the given data: h=10 B and b =7 and x (it may vary which one is bigger)
-----------
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
----------
So if you want the inverse function, you have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
----------
So the new function is:
x(A)=A/5-7
