$0.25

Explanation:

The marginal cost of the sixth pencil is given by the difference in total cost of purchasing 6 pencils from the cost of purchasing 5 pencils. That is, the change in cost caused by the addition of the sixth unit of output:

$MC = \ 1.75-\ 1.50 = \ 0.25$

The marginal cost of the sixth pencil is $0.25
