Answer:
a) Interest earned = $36
New Balance = $336
b) Interest rate = 0.05 or 5%
New Balance = $517.5
c) time t = 5
New Balance = $612.5
d) Principal Amount = $675
New Balance = $783
Step-by-step explanation:
We are given:
a) Principal (P) = $300
Rate (r) = 3% or 0.03
Time (t)= 4 years
Interest earned = ?
The formula used is: 
Putting values and finding interest

So, Interest earned = $36
New Balance = Principal + Interest = 300+36 = $336
b) a) Principal (P) = $300
Rate (r) = ?
Time (t)= 3 years
Interest earned = 67.50
The formula used is: 
Putting values and finding rate

So, Interest rate = 0.05 or 5%
New Balance = Principal + Interest = 450+67.50 = $517.5
c) Principal (P) = $500
Rate (r) = 4.5% or 0.045
Time (t)= ?
Interest earned = $112.50
The formula used is: 
Putting values and finding time

So, time t = 5
New Balance = Principal + Interest = 500+112.50 = $612.5
d) Principal (P) = ?
Rate (r) = 8% or 0.08
Time (t)= 2 years
Interest earned = 108.00
The formula used is: 
Putting values and finding Principal

So, Principal Amount = $675
New Balance = Principal + Interest = 675+108 = $783
Answer:
I exactly don't know the answer
Answer:
A= 429
B= 50
Explanation:
A+B= 479 (take away)
A-B= 379
A-A+B+B= 479-379 (simplify)
2B= 100
I think you know how to do it now..
B=50
A=50+379 ---> 429
This is the substitution method, there are other ways of doing it- and I tried to make this simple. Hope this helped!
Answer:

Step-by-step explanation:
Answer:
No
Step-by-step explanation:
In other words, does the sum of 5/18, 1/9 and 1/6 exceed, equal or come out to less than 1/2?
The LCD of 5/18, 1/9 and 1/6 is 18. Thus, these three fractions are equal to
5/18, 2/9 and 3/18, and their sum is 10/18, or 5/9. Thus, the part of the page covered with text is 1 less 5/9, or 4/9. No, the text does not cover more than half of the page.
