Thank you for the opportunity to help you with your question!

Mass of empty box = m_empty=2.75 kg

Five (5) laptops are packed, each laptop has a mass=m_laptop=1.65 kg

Total mass of 5 laptops = m_5laptop=(5 x 1.65)kg=8.25kg


Total mass including that of box and laptops=m_total,

Now

m_total=m_empty+m_5laptop=2.75kg+8.25kg=11kg

It cost  $40 for the first 5kg and $ 3.15 for each kg above

Total cost = $40+$3.15(11-5)=$40+$3.15 x 6=$40+18.9=$ 58.9

Please let me know if you need any clarification. I'm always happy to answer your questions.
