    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
