Answer:
I believe the correct answer is - The value of a bank account with quarterly compounded interest after 6 years.
I'm not sure if this is 100% correct but hope it helps.
75 would be your answer because it is double and 75 is 100 percent
1/4(r - 5/2) = 1/8
Divide both sides by 1/8 :0
2(r - 5/2) = 1
r - 5/2 = 1/2
r = 1/2 + 5/2 = 6/2
r = 3 Answer
So you divide 0.8 by 6.25 and your answer is 7.8125 and then you add 5.5 minutes of your other number and you get the answer of 13.3125
