Answer 3

Did you copy the problem exactly as it is worded?

Answer 4

Do you mean "... OR 210" or "... TO 210"

Answer 5

yea Or 210

Answer 6

Ok, I'll assume you really meant "... or 210"
That means the increase of 70% is an increase of 210.
That means we are looking for the number 70% of which is 210.

We can word the question better:
210 is 70% of what number?

Answer 7

In math, "is" means "=".
Also, "of" usually means "times".
An unknown number is usually "x".
% means divided by 100, so 70% = 0.70

We can translate the question into a math equation:
210 is 70% of what number?
210=70% * x
210 = 0.70x
0.7x = 210
Divide both sides by 0.7

Answer 8

what do u mean by divide both sides by 0.7 can i get a simple steps im really bad in math...

Answer 9

This is how you divide both sides of an equation by the same number.

The answer is 300.
