The total amount paid on a 35 year loan was $98,000. If the interest rate was 4.1% and compounded monthly, what was the principa
Levart [38]

Answer:

The principal amount was $23,393.45

Step-by-step explanation:

The total amount paid on a 35 year loan was $98,000 at the rate of interest 4.1%

We will calculate Principal amount by this formula

A=P(1+\frac{r}{n})^{nt}

Where A = amount (98,000)

           P = Principal amount (P)

           r = rate of interest 4.1% (0.041)

           n = number of compounding interest monthly (12)

           t = time (35 years)

98,000=P(1+\frac{0.041}{12})^{(12)(35)}

98,000=P(1+0.003416)^{(420)}

98,000=P(1.003416)^{(420)}

98,000 = P(4.189386)

= 4.189386P = 98,000

P = \frac{98000}{4.189386}

P = 23,392.4494 ≈ $23,392.45

The principal amount was $23,393.45

Can someone please help?
almond37 [142]

60 ≥ 35 + 5t

<u>-35 </u><u> </u><u>-35 </u>

<u>25</u> ≥ <u>5t</u>

5 5

t≤5

his mistake was that he used ≤ for at least instead of using ≥. so at end, when I solved, I saw that Sven should spend 5 minutes or less on each scale.

Can anyone please help me with 8th grade math? I will give BRAIN!!!
Anit [1.1K]

The given percentage scores are:

80 , 92 , 91 , 75 , 89 , 84 , 0 , 85

A. Calculate the average

So, the average = (sum of the scores)/(number of the scores)

Sum of the scores = 80 + 92 + 91 + 75 + 89 + 84 + 0 + 85 = 596

The number of the scores = 8

So,

The average = 596/8 = 74.5%

Does the average score really represent her abilities ?

No, because there is outlier which is ( 0 ) which mean it may be absent this test

the other scores are within 75 and 92

Which mean the average is less than the reasonable minimum score

====================================================================

B. Brandee received 78% at the missed test

so, we will find the new mean:

The new sum of the scores = 80 + 92 + 91 + 75 + 89 + 84 + 78 + 85 = 674

The new mean = 674/8 = 84.25%

====================================================================

C. What different did 0% score make ?

So, 0% give us not accurate representation of the student abilities

Does this new mean represent her abilities accurately ?

Yes
