calories burn by the treadmill            =25t
 calories burn by the elliptical trainer  =10e
('t' and 'e' means the time in minutes she spend on each machine )
 .'. total calories she burn                   =25t+10e

since she needs to burn at least 350 calories at the gym,
        $$25t+10e \le 350$$
