A secretary is making an inventory of office supplies. Secretary will indicate 540 pens in inventory.

Solution:

From question, given that

Number of boxes full of blue pen in inventory = 12

Number of pen in 1 box = 45.

Secretary needs to find number of pens in inventory.

Number of pen in 1 box = 45

So number of pens in 12 box = number of pen in 1 box 12

45 x 12 = 540

Hence secretary will indicate 540 pens in inventory.
