The function C(l) = 3 l+ 2
is the cost to order a lip gloss l
,including the flat rate shipping charge. Which of the following represents the cost of purchasing 5 lip glosses? (1 point)
Responses
C(l) = 5
C(l) = 5
l = 5
l = 5
C(5)= 5
C(5)= 5
C(5)
= 3(5) + 2
C(5) = 15 + 2
C(5) = 17
Given that C(l) = 3l + 2
represents the cost of purchasing l
lip glosses, including the flat rate shipping charge, what is the cost per lip gloss? (1 point)

To find the cost per lip gloss, we need to divide the total cost (C(l)) by the number of lip glosses (l).
So, the cost per lip gloss is:
C(l) / l = (3l + 2) / l
However, without knowing the specific value of l, we cannot simplify this expression any further.
To find the cost of purchasing 5 lip glosses, we can substitute l = 5 into the function C(l) = 3l + 2.
C(5) = 3(5) + 2
Simplifying the expression:
C(5) = 15 + 2
C(5) = 17
So, the cost of purchasing 5 lip glosses is 17.
To find the cost of purchasing 5 lip glosses using the given function C(l) = 3l + 2, we can substitute l with 5 in the function and solve for C(5).
So, C(5) = 3(5) + 2 = 15 + 2 = 17.
Hence, the cost of purchasing 5 lip glosses is C(5) = 17.
Therefore, the correct answer is "C(5) = 17".
