The answer is 525

2/3 of residential = 350 customers. so you divide 350 by 2. Which is 175. 175•3= 525

Answer: She has 525 costumers.

Explanation:

We know that the costumer base is
(2)/(3) residential and
(1)/(3) business. This means that:


(2)/(3)=350 residential customers

Let be "x" the total costumers Athy has and "y" the number of business costumers.

Then "x" must be:


x=350+y

Then, in order to find "y" , we need to multiply the number of residential costumers by
(1)/(3) and divide the product by
(2)/(3) :


y=((350)((1)/(3)))/((2)/(3) )\\\\y=175

Substituting we get that "x" is:


x=350+175=525 costumers
