<span>Say the code only needed to be one number long. Going from 0-9, there are ten digits. Therefore, there are ten unique codes.
Now say the code has to be two numbers long. There are ten possibilities
for the first digit, 0-9. But the second digit only has nine
possibilities, since each number has to be different. (The first number
might be 0, so the second can only go from 1-9) For each of the first
ten possibilities, there are nine possibilities for the second. We
multiply those two numbers together, 10 * 9, and we get 90.
Now we just extend the logic. The third number only has eight
possibilities, while the fourth number only has seven. 10 * 9 * 8 * 7 =
5040 possible codes. I hope this helped! has a great day! :)</span>
C - fixed costs; b - costs per bicycle;
c + 110 b = 10,900
c + 130 b = 11,600
c = 10,900 - 110 b
10,900 - 110 b + 130 b = 11,600
20 b = 700
b = 700 : 20 = $35
c + 110 * 35 = 10,900
c + 3,850 = 10,900
c = 10,900 - 3,850
c = $7,050 ( daily fixed costs )
Marginal cost is the cost of producing one more unit of goods ( one more bicycle ).
Answer:
The company`s daily fixed cost is $7,050.
The marginal cost per bicycle is $35.
Answer:
(16/3,-4)
Step-by-step explanation:
- y=-3/4x & y=3/2x -12
- then solve for x which means -3/4x=3/2x-12
- then the value of x=16/3
- put the x value in one equation
- y=3/4(16/3)
- then the value of y=-4
