Each customer of a networking company subscribes to one of two plans: Plan A or Plan B. Plan A costs $50 per month and Plan B costs $150 per month per customer. If the company’s average revenue per customer per month is $100, then what percent of the company's revenue comes from customers with Plan A? Choose the correct choice from the following choices:  A) 25%  B) 50%  C) 37.5%  D) 56.25%  E) 75%
We can show this algebraically:   If there are A customers with plan A, and B customers with plan B, then the total revenue is $50A + $150B.   Since the average customer pays $100, we know that   $100 = ($50A + $150B) / (A + B)   $100(A + B) = ($50A + $150B)   $100A + $100B = $50A + $150B   $50A = $50B   A = B.   Since there are Equal times as many $50 clients as $150 clients, for every $150 received from Plan B customers, $50 is received from Plan A customers, and the percent of revenue from customers with Plan A is:   $50/($50 + $150) = $50/$200 = 25%.   The correct answer is choice (25%).
