Each customer of a networking company subscribes to one of two plans: Plan A or Plan B. Plan A costs $100 per month and Plan B costs $200 per month per customer. If the company’s average revenue per customer per month is $150, then what percent of the company's revenue comes from customers with Plan A?	Choose the most appropriate option:  A) 25%  B) 30%  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 $100A + $200B.   Since the average customer pays $75, we know that   $150 = ($100A + $200B) / (A + B)   $150(A + B) = ($100A + $200B)   $150A + $150B = $100A + $200B   $50A = $50B   A = B.   Since there are Equal times as many $100 clients as $200 clients, for every $200 received from Plan B customers, $100 is received from Plan A customers, and the percent of revenue from customers with Plan A is:   $100/($100 + $200) = $100/$300 = 30%.   Answer 30%
