Answer:
Account B
Value=$21,589.66
Step-by-step explanation:
#We determine the compounded amount after 10 years for each account using the formula:

#For account A:
Given principal is $16,000, i=3% and n=10, m=4:

#For account B:
Given principal is $16,000, i=3% and n=10, m=12:

We compare the amounts after 10 years and get the difference:

Hence, account B has the most value after 10 years and has a value of $21,589.66
Answer:
-11/64
Step-by-step explanation:
Answer:
A = 744 meters B = 489 meters
Step-by-step explanation:
A = B + 255
2B - A = 234
-2B -2B Subract the -2B from both sides
-A = -2B + 234
A = 2B - 234 Divide by -1 to get A alone
B + 255 = 2B - 234 Set both equations equal to each other
- B -B
255 = B - 234
+234 +234
489 = B
Plug 234 in for B in the original equations
A = 489 + 255
A = 744
