Answer:
The salesperson called 200 people this month.
Explanation:
Let us denote the total people that the salesperson called by a variable "x".
Then,
The ratio of successful signups(success ratio) is given as=0.625
Then total no. of successful signups is the product of the success rate and the total no. of signups ,
i.e. Total successful signups =
![0.625*x](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yiyx1n1tpubs9zmskf4x2j4y66xirk7o7c.png)
According to the data given in the question,
The total no. of successful signups this month =125
or ,
![0.625*x= 125](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yrpy61og7yy9e6svuoxkjbqkj4uqmf81d2.png)
or,
![x=(125)/(0.625)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/wdpzu2coc5xubvcmasncj49perz69sb7ee.png)
∴x= 200
So, the salesperson called 200 people, out of which only 125 signed up.
