Constant gross margin percentage NRV method applies the following steps:

a) 1) compute overall gross margin percentage; 2) compute total production costs for each product; 3) compute allocated joint costs

b) 1) compute overall sales value; 2) compute total production cost for each product; 3) compute allocated joint costs

c) 1) COMPUTE OVERALL NRV; 2) compute total production costs for each product 3) compute allocated joint costs

d) none of these
