Sure! Let's solve the problem step-by-step:
1. Total Cost of the Appliance: The total cost of the appliance that Jia wants to buy is ₱495,000.
2. Amount Jia Already Paid: Jia has already paid ₱2,100 for the appliance.
3. Calculate the Remaining Amount: To find out how much more Jia needs to pay, we subtract the amount she has already paid from the total cost.
Remaining Amount = Total Cost - Amount Paid
= ₱495,000 - ₱2,100
= ₱492,900
So, Jia needs to pay ₱492,900 more to purchase the appliance.
