Average cost is measured as a percentage of the list price ofthe hook. h. This is the additional average cost (MC) so the total average cost would he the input price for a hook plus the MC. From this we can infer that the minimum point of the average cost {AC} function oectlrs when a rm has 30% of the wholesale hook market. Furthermore, the minimum point of the additional average cost function {MC} occurs when a rm has 10% of the retail hook market. a. Calculate the HHI and C4 indices for the wholesale hook and retail hook markets. I b. If the current whoIESale market price for a hook is 50% the list price, what is the prot margin for the 11 hook wholesalers?
