Patricia knows that at some point during the calendar year her basic monthly telephone rate increased from \$17.10 to \$18.40. If she paid a total of \$207.80 for basic telephone service for the calendar year, in what month did the rate increase take effect? Answer by calegebra(14)   (Show Source): You can put this solution on YOUR website!There are a couple of ways to solve. One is the chart method where each month is designated with a particular rate--this is too laborous!!!! The best way is to find out how much the \$17.10 rate would be for 12 months \$17.10 * 12 = \$205.20 then compare to Total \$207.80 then work from 11 months at \$17.10 and 1 month at \$18.40 = \$206.50 then work from 10 months at \$17.10 and 2 months at \$18.40 = \$207.80 So, since 2 months at \$18.40 was solution then the fee increased in November (2 months from 1 year)
