A salesperson's ratio of successful signups to the number of people called is 

0.875. 
This month, the salesperson had 
175 
signups. How many people did the salesperson call this month?

0.875x = 175

x = 200

To find out how many people the salesperson called this month, we can use the formula:

Number of signups = Ratio of signups to calls * Number of calls

Let's assign some variables to the given information:

Let x be the number of people the salesperson called this month.
We know that the ratio of successful signups to the number of people called is 0.875, which can be written as 0.875/1.

Now we can set up the equation:

175 = (0.875/1) * x

To solve for x, we can multiply both sides by 1/0.875:

175 * (1/0.875) = x

Simplifying, we have:

200 = x

Therefore, the salesperson called 200 people this month.
