Robert buys a car for $8000. at the end of each year the value of the car has decreased by 10% of its value at the beginning of that year. calculate the value of the car at the end of 7 years.

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
