Hello, here we have three different problems.
00:04
Let's start with the first one, number 12.
00:09
Let's calculate or let's let x indicate the number of pairs of shoes produced and let's develop an mathematical model for the total cost.
00:25
So total cost would be equal to 60 times x plus plus 2000 of fixed costs.
00:40
Now let's develop the model for total profit.
00:47
So total profit would be equal to the difference between price and variable costs multiplied by x and minus fixed cost minus 2000.
01:08
And now let's calculate the break -even point.
01:10
Break -even point for x break even point would be equal to we divide the fixed costs by the difference between price and variable costs and it will be equal to 100 okay now the next question question number 14 what is the break even point the first question let's calculate it we divide again fixed costs by the difference between price and variable costs and break -even point is 4 ,000.
01:58
Now let's calculate the total profit or loss if demand is 300 ,000 and 500 copies.
02:13
So we multiply the difference between price and variable costs by 3500 and subtract the fixed cost.
02:26
And we have negative 20 ,000.
02:33
This is the loss.
02:39
The next question is with demand of 350, 3 ,000, 500 copies, what is the minimum price per copy that the publisher must charge to break even? so now let's try this, let's try to find this price...
