and tel me how can we solve these types

## A number increased 37 ½% gives 33. The *number* is?

## Give a variable name (usually a letter, maybe **
***x*) to the *number*.

*x*

### Now it reads:

## x increased by 37 1/2% ( of x) gives 33, or

## x + (37 1/2 % * x) = 33

## x + (37.5%x) = 33

## 1x + (.375x) = 33

## 1.375x = 33

### Divide both sides by 1.375

## x = 24

Hope this helps. Please vote thumbs up!
