Answer 1

It is time to learn how to keep a ledger like the school canteen does (if you get a bank account, for example):

 

Activity                    Balance

 start of week                 0

Monday-profit 35           35
Tuesday profit 50           85
Wednesday profit 20     105
Thursday loss 10            95
Friday loss 25                70

  end of week               $70

 

Answer 2

Profit:  35+50+20 = 105

Loss:    10 + 25    = -35

                           ----------

Profit:                   $70
