 Question 347508: Maria practiced the recorder for 40 minutes on Saturday. She practiced 10 minutes less in the afternoon than in the mornning. how many minutes did maria practice in the morning? in the afternoon? Answer by fractalier(2101)   (Show Source): You can put this solution on YOUR website!Let M be her morning time and A be her afternoon time. So we know that M + A = 40 and A = M - 10 We can substitute the second into the first and get M + (M - 10) = 40 2M - 10 = 40 2M = 50 M = 25 min and then A = 15 min
