Question

A 28% increase of 150.. whats the new amount?

Answer 1

150  is 100 %
   x   is  28  %
-------------------
150 : x = 100 : 28
100 x = 150 * 28
100 x = 4,200
x = 4,200 : 100
x = 42
150 + 42 = 192
Answer:
The new amount is 192.

Answer 2

Find 28% of 150.
This just means find 28/100 of 150.

So...

150/100=1.5
1.5 x 28=42

Then add this value of 42 to the original amount:

150+42=192

Therefore your new amount is 192.

Hope this helps!☺
