Question 944114
Three students that share a town house 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 roomates. How much did each owe in September. 



Please help me I am completely confused
Thank you

Let amount that September's bill was, be S
Then October's bill was: S - $2.32
Therefore, we get: S + S - 2.32 = 119.56
2S - 2.32 = 119.56
2S = 119.56 + 2.32
2S = 121.88
S, or September's bill was: {{{121.88/2}}}, or ${{{60.94}}}
Amount each owed for September: {{{60.94/3}}}, or about {{{highlight_green("$"20.31)}}}
To be precise, 2 paid: {{{"$"20.31}}}, while 1 paid: {{{"$"20.32}}}
