Greg has 16 clients. Dolores has 75% as many clients as Greg, then
16 - 100%
x - 75%
Write proportion:
[tex]\dfrac{16}{x}=\dfrac{100}{75},\\ \\x=\dfrac{16\cdot 75}{100}=12.[/tex]
This means that Dolores has 12 clients.
Together Dolores and Greg have 16+12=28 clients.
If Robert has 25% as many clients as Greg and Dolores together, then
28 - 100%
y - 25%
Mathematically,
[tex]\dfrac{28}{y}=\dfrac{100}{25},\\ \\y=\dfrac{28\cdot 25}{100}=7.[/tex]
Therefore, Greg, Dolores and Robert have 16+12+7=35 clients.
Answer: 35 clients.
