1)For the situation, show the work for the four steps to solving the inverse variation problem. The graph of a function passes through the point (50,3.6), and y varies inversely as x. Find the value of y when x is 75.

A) Calculate the value of k=xy.

B) Write the equation that represents the inverse variation function.

C) Substitute the given value into the function equation and solve to determine the corresponding quantity.

D) Check your solutions by subtracting both quantities back into k=xy.
