Let's break down the information given in the note to solve the problem:

1. Mrs. Rivera earns ₱16,290.00 per month.
2. She allocates:
   • ₱4,560.00 for monthly house rent and miscellaneous expenses.
   • ₱3,200.00 for education.
3. We need to find out how much is left for food and how much is allocated for food per week.

Step-by-step solution:

1. Total expenses (excluding food): $4,560 + 3,200 = 7,760$
2. Amount left for food: $16,290 - 7,760 = 8,530$
3. Weekly food allocation: There are 4 weeks in a month, so: $\frac{8,530}{4} = 2,132.50$

So, Mrs. Rivera allocates ₱2,132.50 per week for food.
