Question from flor, a student:

Thursday is the most watched night on television with 20 million more viewers than Saturday. the total for both nights is 102 million. how many viewers watch on each of these nights?

Hi Flor,

If the same number watched on Thursday night as Saturday night then since 102/2 = 51, 51 million would watch each of the two nights. If 1 million viewers moved from Saturday night to Thursday night there would be 2 million more viewers on Thursday that Saturday, a 1 million decrease on Saturday and 1 million increase on Thursday. How many million would have to move from Saturday night to Thursday night to make a 20 million difference?
