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. Find the relative rate of change in the home’s value at any time t.I know that it will be dV/dt=VKI know k=-0.01052, would the final answer be -0.-1052=(dV/dt)/V

The original gross margin is (2.50 / 1.00) – 1 = (2.5 – 1) = 1.5  =  150% If you increase the sell price by the same percentage as the growth in cost,you maintain the same percentage of gross margin.  If the cost increases $0.25, that’s a percentage increase of …
