The value of Scarlett’s car, which was 1200 dollars, has decreased by 15 percent. What is her car worth now?

We know that the original value of the car was 1200 dollars. Therefore, 100 percent is equal to 1200 dollars. The car has decreased in value by 15 percent, so we need to find 15 percent of 1200. We can calculate 10 percent by dividing by 10, as 100 divided by 10 equals 10. 1200 divided by 10 is equal to 120. Therefore, 10 percent is equal to 120. Halving this would give us the value of 5 percent, as 10 divided by two is equal to five. 120 divided by two is equal to 60. Therefore, 5 percent is equal to 60 dollars.

We can calculate 15 percent of the value by adding the value for 10 percent and the value for 5 percent. 120 plus 60 is equal to 180. Therefore, 15 percent of 1200 dollars is 180 dollars. As the car has decreased in value, we need to subtract 180 dollars from 1200 dollars. 200 minus 180 is equal to 20. Therefore, 1200 minus 180 is equal to 1020. Following a 15 percent decrease, Scarlett’s car is now worth 1020 dollars.
