Hi there!

I was stuck on this question for homework. Could please give me a step by step instruction on how to approach this question.

At the start of 2014 mikes car was worth 12000. The value of the car decreased by 30% every year. Work out the value of the car at the start of 2017.

Thanks :D

2015:
[tex]12000 - 100\% \\ x - 70\% \\ x = \frac{12000 \times 70}{100} = 12000 \times 0.7 = 8400[/tex]
2016:
[tex]8400 - 100\% \\ x - 70\% \\ x = 8400 \times 0.7 = 5880 [/tex]
2017:
[tex]5880 - 100\% \\ x - 70\% \\ x = 5880 \times 0.7 = 4116[/tex]
