What is the final amount if 490 is increased by 15% followed by a further 14% increase?

Give your answer rounded to 2 DP.

642.39

Step-by-step explanation:

To get the increase, first get the given % of the amount and then add the result gotten to the amount

So, firstly

15% of 490

Make 15% a decimal by dividing it by 100

15/100 x 490

0.15 x 490 = 73.5

Increase = 490 + 73.5

= 563.5

Further so,

14% increase of 563.5

We do same as we did above

14/100 x 563.5

0.14 x 563.5 = 78.89

Therefore,

Increase = 563.5 + 78.89

= 642.39
