Question

In order to receive a b in your english class, you must earn more than 350 points of reading credits. last week you earned 120 points. this week you earned 90 points. how many more points must you earn to receive a b or better in english?

Answer 1

120 + 90 = 210 points
350 - 210 = 140 OR
   351 - 210 = 141  (if it must be more than 350, you need at least 351 points total, or 141 more points, to get a grade B)
