Dimitri is buying a car. he chooses option 1 to add a new sound system to his car. what integer represents the change from the base price of the car to its final price?

Integers are simply numbers (whether positive or negative) without decimal points. The integer that represents the change to the final price is -1100

Given that:

The base price of Opt. 1 is +$1400.00

The markdown is -$1100.00

The markdown represents the change from the base price to the final price
