Answer:
![r= [(\frac{A}{2500}) ^\frac{1}{2} -1]](https://tex.z-dn.net/?f=r%3D%20%5B%28%5Cfrac%7BA%7D%7B2500%7D%29%20%5E%5Cfrac%7B1%7D%7B2%7D%20-1%5D)
Step-by-step explanation:
Given data
Principal = $2500
time t= 2 years
Required
the rate r
Given the expression for the balance 2500(1+r)^2
Hence
we can make r subject of formula
![r= [(\frac{A}{P}) ^\frac{1}{t} -1]](https://tex.z-dn.net/?f=r%3D%20%5B%28%5Cfrac%7BA%7D%7BP%7D%29%20%5E%5Cfrac%7B1%7D%7Bt%7D%20-1%5D)
Hence, for any value of A, we can find the rate using the expression above

Step-by-step explanation:
Answer:
Monthly Living Expense = 2375
Monthly Fixed Expense = 1975
Step-by-step explanation:
Let monthly living expense be "x"
and monthly fixed expense be "y"
<u>"monthly living expenses were 400 more than his monthly fixed expenses":</u>
x = 400 + y
<u>"Richard total monthly expenses were 4350":</u>
x + y = 4350
Putting Equation 1 in Equation 2:
(400 + y) + y = 4350
400 + 2y = 4350
2y = 3950
y = 1975
Now, x = 400 + y = 400 + 1975 = 2375
