The percentage of reduction is 17%
<u>Explanation:</u>
Original price = $21
Reduced price = $17.43
Percentage of reduction = ?
Difference in price = $21 - $17.43
= $3.57
Percentage of reduction =
Therefore, percentage of reduction is 17%
velocity is the slope (which can be calculated after finding the derivative) → given function f(x), velocity = f'(x).
acceleration is the slope of the velocity (which can be calculated after finding the derivative of the velocity) → given function f(x), acceleration is f''(x)

1a) A → B
f(x) =
f'(x) =
1b) B → C
f(x) =
f'(x) = = -5
1c) C → D
f(x) = 20
f'(x) = 0
Hope this helps!
