Original #: 950
New #: 1,520
If it is percent of increase, you would do new amount - original amount over original amount.
1,520 - 950 / 950 = 570 / 950
0.6 or 60%
3x+x=y
3(-3)+(-3)=y
-9-3=y
-12=y
Therefore the value of x3+x is -12
What is 8 meters increased by 28%?
Well, first, you need to convert 28% to a decimal by moving the decimal two to the left by dividing by 100
28÷100=.28
or
28%⇒28⇒.28
Then you multiply
8 meters times .28

Then you add 2.24 to 8m (since its the original number)

Your answer is 10.24m
