grade varies directly with studying and inversely with going to the mall.

is the answer 48hrs?

**Reiny**, Tuesday, August 2, 2011 at 1:10pmMark = k(s)/m, where s is number of hrs studying, m is the number of hrs at the mall, and k is a constant

given: Mark = 85, s=10, m=4

85 = k(10)/4

k = 34

Mark = 34s/m

96 = 34s/17

s = 48 hrs

(a rather silly question)
