C(l)

Answer 1

To find the cost per lip gloss, we need to divide the total cost of purchasing l lip glosses by the number of lip glosses.

C(l) = 3l + 2

To find the cost per lip gloss, we divide both sides of the equation by l:

C(l)/l = (3l + 2)/l

The l on the right side of the equation cancels out:

C(l)/l = 3 + 2/l

So the cost per lip gloss is 3 + 2/l.
