Did she receive the correct amount for her change? Prove your answer by showing your solution below in an orderly manner.
Answer:
First step, we will calculate all the expenses of Jannah.
- ₱1,200 + (₱849.75 × 2) = N
Solve:
- ₱1,200 + (₱849.75 × 2)
- =₱1,200 + (₱1,699.50)
- =₱2,899.50
Therefore, the total expenses of Jannah are ₱2,899.50
Next step, we will subtract the total expenses of Jannah from ₱3,000.
Solve:
- ₱3,000–₱2,899.50
- =₱100.50 – change that Jannah received from the cashier.
₱100.50 ✓
Conclusion:
Jannah received the correct amount of change.
