I looked for promos and discounts (20%, 15%, 10%, 5%) to reduce the total without sacrificing quality. Choosing one homemade main dish and pairing it with a discounted protein kept the menu satisfying but affordable. I also controlled the number of drinks and supplies to what we realistically need, then selected a useful gift on sale. Finally, I made sure the grand total (₱2,964.05) is under budget and kept a ₱35.95 buffer for any small price changes. This plan balances enjoyment, practicality, and cost control.Step-by-step explanation:have a nice day, kindly brainliest ;)
