Its 4 because 2+2 is 4 and then you're subtracting 2 and then adding 2 again so its 4
It would be: 18/15 * 100 = 1800/15 = 120%
I might not be understanding what you mean but I think it is by counting 10s. 170,180,190,200,210,220,230,240,250,260,270,280,290,300,310,320,330,410.
Solution:
Given:
The value of a car after t - years will depreciate.
Hence, the equation given represents the value after depreciation over t-years.
To get the rate, we compare the equation with the depreciation formula.
Hence,
Therefore, the value of this car is decreasing at a rate of 6%. The purchase price of the car was $16,300.
Use Math..way. Put in equation, hit solve, will give u val. for N
