If Laura scored only a 59 on the midterm, what is the minimum score would she have to get on the final in order to get a C or better?

**Reiny**, Monday, June 3, 2013 at 8:46pm(1/3)(59) + (2/3)F ≥ 70

times 3

59 + 2F ≥ 210

2F ≥ 151**F ≥ 75.5**

check: suppose she got 80

Final mark = (1/3)59 + (2/3)80= 73 , OK

suppose she got 75

Final mark = 59/3 + (2/3)(75 = 69.666... which is < 70
