Reid Chung · Answer 1

The combined percentage for the cost of food is 81%, housing is 75% and for the transportation is 48%.

You just have to add both the cost of a certain unit (food/housing/transportation) increase and the percentage spent by an average salaried worker on a certain unit (food/housing/transportation).
