Suppose that y varies jointly with x and %. Find the constant of proportionality k if z = 115.2 when y = 4 and x = 18. Using the k from above, write the variation equation in terms of x and y. Using the k from above, find z given that y = 8 and x = ?. If needed, round the answer to 3 decimal places. Enter DNE for Does Not Exist and oo for Infinity.
