you sell used cd at a local flea market. it costs p500 to rent a booth for a day. you spent p150 on lunch, and you make p6,230 selling cds. if you have p7,120 at the end of the day, how much money did you have at the start of the day?

You had ₱1,540 at the start of the day.

How to see it step by step

1. Add your expenses for the day
   • Booth rent: ₱500
   • Lunch: ₱150
   • Total expenses: 500+150=650500+150=650500+150=650 pesos.

2. Find your profit from selling CDs
   • Sales from CDs: ₱6,230
   • Minus expenses: 6,230−650=5,5806,230-650=5,5806,230−650=5,580 pesos profit.

3. Use your final money to get your starting money
   • Money at the end of the day: ₱7,120
   • This is: starting money + profit
   • So starting money =7,120−5,580=1,540=7,120-5,580=1,540=7,120−5,580=1,540 pesos.

So the amount you had before renting the booth, buying lunch, and selling CDs was ₱1,540.
