What do i need do do can someone me

Please overview the solution provided, it will only help you :)

the empty box weighs 2.75 kg

the store is packing 5 of the same laptops that weigh 1.65 kg each in said box

combined mass:

1.65*5=8.25kg

8.25+2.75=11 kg

it cost 40$ for the first 5kg and 3.15$ for EACH kg over kg

11kg>5kg

11-5=6

40+3.15(6)=58.90

Hence, the cost to ship the package was $58.90.

This problem may seem difficult, but essentially you just have to carefully read and work out the problem. Maths isn't so hard.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
