Hi, i believe it is 7.15625 lmk if i’m right

7.15625

Step-by-step explanation:

If the company used rectangular prisms it would take 40 boxes (2400/60) to hold 2,400 pencils which would cost $20 (40 times 0.50). If they used cylindrical containers, they would need 30 containers (2400/80) for a total of $22.50 (30*0.75).

To minimize the cost the company should go with rectangular prisms as they are the most cost effective.
