There are 2 significant figures (sig figs) which are the two '5' digits. The zeros aren't considered sig figs because we can write the number as 5.5 * 10^8 to represent the exact same idea. The 0's are simply placeholders to tell how big the number is, not necessarily how accurate it is. If the 0s were between the decimal point and a nonzero value, then the 0s would be significant. If the 0s were to the right of the decimal, then they would be significant.

Answer:
1000 x .15 = 150 The car will lose 15% value after the first year which is $150. Subtract 150 from 1000 and the new value would be $850.
5020 x .15 = 753 This car lost 15% after the first year which is $753. Subtract 753 from 5020 and the new value would be $4287.
