What's the problem? Just write an expression for each company, set them equal, and solve the equation.

company A charges 27.95 + .12m for m minutes

company B charges 12.95 + .32m for m minutes

27.95 + .12m = 12.95 + .32m

15.00 = .20m

75 = m

check:

27.95 + .12(75) = 36.95

12.95 + .32(75) = 36.95
