Question

A drum set originally costs $500, but it is on sale for 20% off. If a customer buying the drum set has a $70 gift card, what will her final price be on the drum set?

Answer 1

20% of 500 is 100 so 500-100=400 and then with the 70 dollar gift card you have to do 400-70 which is 330. The final price is $330

Answer 2

20% of $500 is $100, so you take away $100 from $500.
= 500 - 100

This leaves you $400. When the customer buys the drum set, you take $70 off of $400;

400 - 70
which leaves you with $330 as the final price.
