The total monthly cost, T(m), of Teresa’s cell phone plan, in dollars, is calculated using the function T(m) = 59.95 + 0.15m, where m is the number of minutes she uses each month. The total monthly cost, R(n), of Randy’s cell phone plan, in dollars, is calculated using the function R(n) = 29.95 + 0.35n, where n is the number of minutes he uses each month. Teresa used 406 minutes last month. Randy used 327 minutes last month. How much less did Teresa owe than Randy?
