The Mathematics of Budgeting Red's Allowance

For this week:
Food - P 440.00
Readings - 69.00
Extra Expenses - 185.00

I came from Tuguegarao, Nueva Viscaya. My allowance is sent by bus so I should make sure that my expenses fit for the week.
I was sent to UP Baguio because of the low tuition rates. My parents could not afford to send be to other prestigious universities. I have 4 brothers and sisters and my parents' budget are tight. For this reason I only receive P 950 for a weeks expenditures.
I get P 150 for weekdays and P 100 on weekends because I spend less, or I need not spend extra. But because I have extra activities, I also need to spend wisely. And in this post you will see how I budget my weekly allowance.Ü
I live in a boarding house in Lower Cabinet Hill which is near to UP. SO I just walk when I go to school and I avoid goind to places where I need to ride a cab or jeep to get back to my place.
Every morning I drink hot chocolate or coffee and take in bread that I buy from the nearest bakery. There are a lot of carinderias near my boarding house, all serve affordable and yummy healthy food, where I can eat P 25-30 meals instaed of spending P 38 for lunch in school.
Good thing Mama sent me bigas (rice grains) two weeks ago so I just needed to buy viands from the nearvy carinderia.
In UP, professors make use of many books. There are a lot of readings and last week I spent P 69 on photocopied readings, which are quite not clear or the prints are fading. But anyway, it's okay.
