Jeremiah Company has established the following standards for one unit of its metallic product, the
wonder camera tripod (stainless edition):
                         Inputs                                                         Standards
                Direct materials                                      3 metal bars at P2 per bar
                Direct labor               ½ labor hour at P10 per hour
   At the start of the month, the budget includes a planned production of 100 units of tripod based on
    normal capacity.
   At the end of the month, actual production was 120 units of tripod, which resulted to using 400 bars
    of metal, purchased at a cost of P2.10 per bar.
