Three students that share a townhouse find that their electric bill for October is $2.32 less than the September bill. The total of both bills is $119.56, and each bill is split evenly among the roommates. How much did each owe in September?
Answer provided by our tutors
Let 'x' represent the bill in September then the bill in October is x - 2.32.
Since both bills together are $119.56 we have:
x + x - 2.32 = 119.56

x = $60.94
The bill is split evenly among 3 people:
