Answer:
Tk 173.25
Step-by-step explanation:
The firm will break even if its cost is equal to its revenue. That is, the price of each item sold must equal the cost of producing it. To cover the fixed cost, a share of it must be added to each of the items sold. Then the break-even price for 80 items is ...
price = variable cost + share of fixed cost
price = Tk 60.75 +9000/80 = Tk 60.75 +112.50 = Tk 173.25
Answer:
The new slope is 1
Step-by-step explanation:
The slope of any two points can be found by:
![slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=slope%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
Finding slope of (3,7) (4,9)
![slope=\frac{9-7}{4-3}\\slope=\frac{2}{1}\\slope=2](https://tex.z-dn.net/?f=slope%3D%5Cfrac%7B9-7%7D%7B4-3%7D%5C%5Cslope%3D%5Cfrac%7B2%7D%7B1%7D%5C%5Cslope%3D2)
Finding slope of (4,9) (5,11)
![slope=\frac{11-9}{5-4}\\slope=\frac{2}{1}\\slope=2](https://tex.z-dn.net/?f=slope%3D%5Cfrac%7B11-9%7D%7B5-4%7D%5C%5Cslope%3D%5Cfrac%7B2%7D%7B1%7D%5C%5Cslope%3D2)
So, the slope of the line is 2
Now if slope is divided by 2, new slope will be:
![slope = \frac{2}{2}\\slope=1](https://tex.z-dn.net/?f=slope%20%3D%20%5Cfrac%7B2%7D%7B2%7D%5C%5Cslope%3D1)
So, The new slope is 1

Answer:
230,300 different selections.
Step-by-step explanation:
If the order does not matter, the number of possible different selections is determined as the combination of choosing four numbers out of 50:
![n=\frac{50!}{(50-4)!4!}\\\\n=\frac{50*49*48*47}{4*3*2*1} \\\\n=230,300\ combinations](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B50%21%7D%7B%2850-4%29%214%21%7D%5C%5C%5C%5Cn%3D%5Cfrac%7B50%2A49%2A48%2A47%7D%7B4%2A3%2A2%2A1%7D%20%5C%5C%5C%5Cn%3D230%2C300%5C%20combinations)
There are 230,300 possible different selections.
