Answer:
As the price rises from 20 $ to 45 $ so my frequency of visiting in friends home will also decreases. It will become once in month.Previously it was once in a week.It does not effect our relation.
There will be no change as the tuition classes i needed it will remain same. It can not change with price.As it is necessity.
If i will receive 300$ per month then my consumption of some extra thing will increase but it does not change my behavior.
As i m receiving extra money so if price of food double then also it will not effect on my food.
I hope this helps you my dude <3
