Question

please help
Molly is having her birthday party at Pizza Party Palace. The costs involved are listed below. Pizza Party Palace requires a 20% deposit prior to the date of the event. If the deposit has been paid, how much is still owed for Molly's party?

Party Prices
• Food & Drink $300
• Game Tokens $125
• Other $85
$102
$306
$408
$204

Answer 1

Add up the total price of the party.

300+125+85= 510

If there has to be a 20% deposit, find 20% of 510

510(.2)= 102

This is the amount that has already been paid, subtract this from the total cost of the party

510-102=408

Or, if you want, since you know 20% has already been paid, and 80% still needs to be paid, you can just do

510(.8)=408
