Well, I have never seen a question posed this way, but let's check it out by trial and error.
1^3 = 3
2^3 = 8
3^3 = 27 Hey! There's one. And the ones digit ends in 3.
Let's try another number that ends in 3 and see if it works as well.
13^3 = 2197 Wow. It works again. I never noticed this before, so you taught me something new.
I will test one more.
33^3 = 35937 Bingo. I think we have a winner.
Answer:
We conclude that the total amount accrued, principal plus interest, from compound interest on an original principal of $2500 at a rate of 5% per year compounded 6 times per year over 8 years is $3723.38.
Step-by-step explanation:
Given
Principle P = $2500
Interest rate r = 5% = 0.05
Time period t = 8 years
To determine
Accrue Amount A = ?
Using the compound interest equation
where:
A represents the Accrue Amount
P represents the Principal Amount
r represents the interest rate
t represents the time period in years
n represents the number of compounding periods per unit t
Important tip:
- Given that the interest is compounded 6 times each year, therefore, the value of n = 6.
now substituting P = 2500, r = 0.05, t = 8 and n = 6 in the equation
∵
$
Therefore, we conclude that the total amount accrued, principal plus interest, from compound interest on an original principal of $2500 at a rate of 5% per year compounded 6 times per year over 8 years is $3723.38.
If you ate a third of the box and there ARE 16 left then you started with 48 originally
Rewrite 5% as a decimal and then multiply by 60.
X = 0.05 x 60
