When m is equal to 2 and p is equal to 1 fourth , j is equal to 32 If j varies directly with m and inversely with p , what is the constant of variation?

Since j varies directly with m and inversely with p, write j = km/p, where k is the constant of variation. Substitute j = 32, m = 2, and p = 1/4: 32 = k(2)/(1/4) = 8k. Dividing by 8 gives k = 4, so the constant of variation is 4 (choice C).
