Okay, here we have a problem about cost and the answers you have given here are correct.
00:09
I don't know what your question is, but let me just maybe you want to verify to confirm that your answers are correct.
00:19
Anyway, so what we have, we have someone selling t -shirts.
00:24
The marginal cost to produce one dessert is $3 .5.
00:29
Dollars total cost to produce 40 t -shirts is 220 and the price the selling price is eight dollars per t -cert so that means the the total cost if x is units sold or produce then the total cost of producing x units of t -serts is 3 .5x plus the fixed cost.
01:07
We are not giving the fixed cost, but we are told that in order to produce, that the total cost for producing 40 t -shirts is 220, which means now that we should have that 3 .5 % of, 40 plus fixed cost is 220 and that gives us that the fixed cost is 220 minus this is 3 .5 excuse me this is 220 here 220 minus 3 .5 times 40 is 140 is 140.
02:06
So the fixed cost is going to be 80.
02:10
And that means the cost function is exactly what you are having here.
02:15
The cost function is 3 .5x plus 80.
02:21
Okay...
