That leaves 15,000 left in sales where the 7% commission applies.

Adding these two together we get a total of

Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+4=3x+8
Step 1: Subtract 3x+8 from both sides.
x2+4−(3x+8)=3x+8−(3x+8)
x2−3x−4=0
Step 2: Factor left side of equation.
(x+1)(x−4)=0
Step 3: Set factors equal to 0.
x+1=0 or x−4=0
x=−1 or x=4
Answer:
x=−1 or x=4
Answer:
Step-by-step explanation:
C
We can express the recurrence,

in matrix form as

By substitution,

and continuing in this way we would find that

Diagonalizing the coefficient matrix gives us

which makes taking the
-th power trivial:


So we have

and in particular,




Answer:
y = 
This is the correct answer because I got it right.
