This is the 2nd post you made without showing any work. You do realize that this forum is a math help site where we help students solve their problem. This is not a drop off your homework and come back later for the complete solutions type of site.

We prefer to help you solve the problems with assistance from helpers on the forum.

To help you at least make a start on this question:

Let’s say May sales = $100
Add on 30% of $100 to $100 and what do you get? This figure is June Sales.
Now take this figure and subtract 10% of it. What do you get?
This figure is July sales.
Now find the difference between May and July sales figures.
What is the difference in sales between June and July?

Once you have posted back some answers we can talk about how to proceed further.
