Step 1

The material cost is $5 per kg for material A and $2 per kg for material B. The handle cover weighs 4g = 0.004kg. For PVC: Yield rate = 80% = 0.8 Material A cost per part = 0.004 kg * $5/kg = $0.02 Material B cost per part = 0.004 kg * $2/kg = $0.008 Total Show more…

00:01 So here we have a costing exercise for steel versus aluminum.

00:08 So we need to produce 8 ,000 of these things.

00:11 And we're told a whole bunch of information, right? steel is going to be 380 per kilogram and aluminum is going to be 870 per kilogram.

00:23 Right? so the steel unit weighs 110 grams and which is equal to 0 .3.

00:32 1 .11 kg.

00:34 And the aluminum unit weighs 30 grams, which is equal to 0 .03 kg, right, dividing by 1 ,000.

00:44 When steel is used, 50 units can produce per hour.

00:49 Okay, so first of all, let's find the cost of the weight, right? so this means that the weight of 8 ,000 is equal to 0 .11 times 8 ,000, which, is equal to, i mean i should be able to do that in my head, right, but it's early morning here and i'm going to use a calculator for a lot of parts of this question anyway.

01:16 This is of course 880, brilliant.

01:19 Means that we need 880 kilograms, right? and at 380 per kilogram, right, this gives us a total cost in terms of steel of, 3 ,344.

01:44 So for aluminum, this is 0 .03 times 8 ,000.

01:50 That is equal to 240 kilograms.

01:55 The cost per kilogram of aluminum is 870.

01:59 So this gives me a cost of aluminum of, of again run to my calculator, 2088.

02:15 So this is the cost of the raw material that we need...
