The median value of a home in a particular market is decreasing exponentially. If the value of a home was initially $240,000, then its value two years later is $235,000. Answer the following.1) Determine when the value of the home will be 90% of its original value.Would the equation be set up like so: V=240e^.09t? 2)Determine the rate at which the value of the home is decreasing one year after it is valued at $235,000. Include units in your answer, and round the final value to the nearest dollar.What I know so far: V=240e^(-0.01052)tWould you make t=1 and v=235?3)The relative rate of change in a quantity is defined as the rate of change for that quantity divided by the quantity present.
