Question

What is the final amount of 777 is decreased by 12% followed by a 4% increase? Give your answer rounded to 2dp.

Answer 1

Answer:

711.11

Step-by-step explanation:

Method 1

If 777  is decreased by 12%. the number would now be (100% - 12%) 88% of what it was originally

0.88 x 777 = 683.76

683.76 is increased by 4%.  683.76 would now be (100 + 4%) 104% of what it originally was

683.76 x 1.04 = 711.11

Method 2

12% x 777 =

0.12 x 777 = 93.24

777 - 93.24 = 683.76

4% x 683.76 = 27.3504

683.76 + 27.3504 = 711.11
