Question

What is the final amount if 860 is increased by 6% followed by a 9% decrease? Give your answer rounded to 2 DP.

Answer 1

735.64

Explanation:

6% of 860 = 51.6

860-51.6 = 808.4

9% of 808.4 = 72.756

808.4 - 72.756 = 735.644

Answer 2

Explanation:

Increased amount = 106% of 860 = 1.06 * 860 = 911.60

Amount after decrease = 91% of 911.60 = 0.91* 911.60 = 829.556 = 829.56
