The percent abundance of each kind of candy tells you how many of each kind of candy there are in every 100 particles. what does relative abundance tell you?

Percentage abundance describes how many candies (object) are present within every 100 particles.

Relative abundance, however, is used to describe the abundance of a certain isotope of the object (candies in this case) within the given sample of the same object.

Suppose J, K, L, M, N are points on the same line.

MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14

Since LK = MK and LK = 7x - 10, then

7x - 10 = 8x - 14

8x - 7x = -10 + 14

x = 4

LJ = MK + KJ

MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18

LJ = 18 + 28 = 46
