How much more would $8,000 earn in four years compounded daily at 5% than compounded annually at 5%?
QveST [7]

Answer:

Given the statement:

8,000 earn in four years compounded daily at 5%

To find the amount we use formula:

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

where P is the principal , A is the amount , n is number of times compounded per year and t is the time in year.

Here, Principal(P) = $8000, r = 5% and n = 365

Substitute these given values we get;

A_1= 8000(1+\frac{5}{365})^{365 \cdot 4}

A_1= 8000 \cdot 1.000137^{1460}

A_1= 8000 \cdot 1.22141

Simplify:

A_1= \$9771.28

To find the Interest we use formula:

I_1= A_1-P

I_1= 9771.28 -8000 = \$1771.28

It is also given that:

8,000 earn in four years compounded annually at 5%.

Here, P = $8000, r = 5% , t =4 year and n = 1

Using the same formula to calculate the amount:

A_2 = 8000(1+\frac{5}{1})^{1 \cdot 4}

A_2= 8000(1.05)^4

Simplify:

A_2= \$9724.05

To find the Interest :

I_2= A_2 - P

I_2= 9724.05 - 8000= \$1724.05

Then;

I_1-I_2 = 1771.28-1724.05 = \$47.23

Therefore, $47.23 more would  $8,000 earn in four years compounded daily at 5% than compounded annually at 5%

KIM [24]

F<span>or every 1,000 feet you go up in elevation</span>, <span>the temperature decreases by about 3.3°F</span>

 

Given:

Temperature at the bottom of the mountain is 74°F

The top of the mountain is 5500 feet above you

 

Change (reduction) in temperature is 3.3 X 5500 / 1000

= 18.15°F

 

Temperature at the top of the mountain is 74°F – 18.15°F

= 55.85°F
