Convert 88 lbs. to kgs.:

88 lbs ÷ 2.2 lbs/kg. = 40 kg.

1)First 20 kg = Php 1,100

2)Subtract the first 20 kg from total 40 kg:
  40 kg. - 20 kg = 20 kg, remaining kg

3) For every succeeding 2 kg, the cost is Php60.  Multiply by 20 remaining kg.
    (Php 60/2kg) x (20 kg)
    = (Php 30/kg) x (20 kg)
    =  Php 600

4)  Add the freight charges:
    Php 1,100 + Php 600 = Php 1,700, freight charges for 88 lbs.
