You can put this solution on YOUR website!

We can give a formula,Y=P-3000%28X%29
wheresystem%28Y=Value_after_X_years%2CP=Present_Value%2CX=Number+of_Years%29
After 1 year:
Y=24000-3000%281%29=24000-3000=$21,000.00
After 2 years:
Y=24000-3000%282%29=24000-6000=$18,000.00
After 3 years:
Y=24000-3000%283%29=24000-9000=$15,000.00
And so forth....
*Note: After "8" years, I think it's about time to buy a NEW car. Substitute X=8 and see why?
Thank you,
