Yakvenalex [24]

Answer:

The remaining tea = 0.305 kg

Step-by-step explanation:

The mass of Tea pack = 0.345 kg

The mass of tea taken = 40 g

as

  • 40 g = 0.04 kg

Therefore, all we need is to subtract 0.04 kg from 0.345 kg to determine the tea left:

i.e.

Remaining Tea left = Total tea - Tea taken

                                = 0.345 - 0.04

                                = 0.305 kg

Therefore, the remaining tea = 0.305 kg
