Answer:
2020
Happy New Year!
Explanation:
Paulo Received his car in 2010. 2 years later his car started depreciating. Our goal here is to find the year that his car is worth less than 25% of what he actually paid. Let say he paid $7000 for the car multiply that by 0.25 and you 25% of what he paid which is $1750. That is the goal number. So we can take 15% off of 7000 every year starting from 2012.
2012 - $5950
2013 - $5057.50
2014 - $4298
2015 - $3653
2016 - $3105
2017 - $2639
2018 - $2243
2019 - $1907
2020 - $1621
I hope this helps you.
