Question

2

(a) In 2016, a company sold 9600 cars, correct to the nearest hundred.
(i) Write down the lower bound for the number of cars sold.

Answer 1

The lower bound for the number of cars sold in 2016 is 9500.

Step-by-step explanation:

To find the lower bound for the number of cars sold, we need to round down the given number to the nearest hundred. Since the company sold 9600 cars, rounding down to the nearest hundred would give us 9600 - 100 = 9500. Therefore, the lower bound for the number of cars sold is 9500.

Answer 2

Answer: lower bound = 9550

Step-by-step explanation:

Since the number is rounded to the nearest hundred, the actual value is somewhere between 9550 (which rounds up to 9600) and 9649 (which rounds down to 9600).

The lower bound is: 9550

The upper bound is: 9649
