Answer:
28%
Step-by-step explanation:
3600$ × 20%
=3600 ×(20/100)
=3600 × 0.2
= 720
Actual Price = 3600 - 720
= 2880
Profit is at 4000$ = 4000 - 2880
= 1120$
%profit = (1120/4000) × 100
profit = 28%
Answer:
- no real solutions
- 2 complex solutions
Step-by-step explanation:
The equation can be rearranged to vertex form:
x^2 -4x = -5 . . . . . . . . . subtract 4x
x^2 -4x +4 = -5 +4 . . . . add 4
(x -2)^2 = -1 . . . . . . . . . show the left side as a square
x -2 = ±√-1 = ±i . . . . . . take the square root; the right side is imaginary
x = 2 ± i . . . . . . . . . . . . . add 2. These are the complex solutions.
