Group Title
A telephone company charges customers a certain amount for the first minute of a long distance call and another amount for each additional minute. A customer makes two calls to the same city—a 31minute call for $1.94 and a 13minute call for $0.86.
If there is a federal tax rate of 3.7% and a state tax rate of 7.4% on all long distance calls, find, to the nearest minute, the longest call to the same city whose cost will not exceed $9.00.

I'd say add the taxes together 3.7+7.4 = 11.1% then the equation becomes y = (11.1/100)*( 0.14 + 0.6(m1) ) does that work?

@xon1300 In your formula, \(y\) would only be the tax. It wouldn't include the cost of the call.

so \[y = (111.1/100)*( 0.14 + 0.06(m1) )\] when y=9 m= what?
