Answer: 93 units should be ordered.
Step-by-step explanation:
Since we have given that
Standard deviation = 4
Average = 30 units
Number of weeks in order interval = 3
Desired service level = 97.5%
Number of units on hand = n = 43
So, the expected value would be
![E[x]=30\times (3+1)+1.96\times 4\sqrt{3+1}-43\\\\E[x]=30\times 4+1.96\times 4\times 2-43\\\\E[x]=120+15.68-43\\\\E[x]=92.68\approx 93](https://tex.z-dn.net/?f=E%5Bx%5D%3D30%5Ctimes%20%283%2B1%29%2B1.96%5Ctimes%204%5Csqrt%7B3%2B1%7D-43%5C%5C%5C%5CE%5Bx%5D%3D30%5Ctimes%204%2B1.96%5Ctimes%204%5Ctimes%202-43%5C%5C%5C%5CE%5Bx%5D%3D120%2B15.68-43%5C%5C%5C%5CE%5Bx%5D%3D92.68%5Capprox%2093)
Hence, 93 units should be ordered.
Answer:
(a) A = 700×1.015^t
(b) 36.2 years
Step-by-step explanation:
(a) Each year, the account value is multiplied by (1 + 1.5%) = 1.015. Repeated multiplication is signified using an exponent. In t years, when the account has been multiplied by 1.015 t times, the account value will be ...
A = $700×1.015^t
__
(b) You want to find t when A=$1200. Logarithms are involved.
1200 = 700×1.015^t . . . . use 1200 for A
1200/700 = 1.015^t . . . . . divide by 700
log(12/7) = t×log(1.015) . . . . . take logarithms
log(12/7)/log(1.015) = t ≈ 36.2 . . . . divide by the coefficient of t
It will take about 36.2 years for the account balance to reach $1200.

Answer:
675
Step-by-step explanation:
750 gets turned into 7.50, or 7.5. Then you multiply 7.5 by 90 to get your answer
