Person A earns $5000 and Person B earns $3000. What are our income weights?

Person A's weight is 0.625 (62.5%) and Person B's weight is 0.375 (37.5%).

We have $2000 in shared bills. Based on our weights of 0.6 and 0.4, how much should each pay?

Person A is responsible for $1,200 and Person B is responsible for $800.

I bought a new sofa for $600. How much should we add to our monthly shared expenses if we split it over 6 months?
