The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
solve for P

Answer:
Figure 1's surface area: 550 
Figure 2's surface area: 530
Figure 3's surface area: 790
So, the order of the figures' surface areas is: Figure 2 < Figure 1 < Figure 3.
Step-by-step explanation:
Bearing in mind that the surface area of a 3D object is the total area of its surface (that is the sum of the areas of its faces), we can count the number of distinct shapes in each figure, calculate their areas and add them up. Be careful not to add the faces that are "inside".
<u>Figure 1</u>
Its surface area consists of 13 squares of 5x5
and 3 rectangles of 15x5. So, its surface area is (13x25 + 3x75)
<u />
<u>Figure 2</u>
Its surface area consists of 6 squares of 5x5, 3 rectangles of 17x5, 1 rectangle of 13x5 and 2 triangles of base 12 feet and height 5 feet. So, its surface area is (17x5x3+6x5x5+13x5+12x5x2:2)
<u />
<u>Figure 3</u>
Its surface area consists of 2 rectangles of 12.5x5
, 1 rectangle of 11x5, 2 triangles of base 12 feet and height 5 feet, 1 rectangle of 11x13, 2 rectangles of 12.5x11 and 1 rectangle of 12x11.
So, its surface area is (2x12.5x5+11x5+2x12x5:2+11x13+2x12.5x11+12x11)

The simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.
According to the question,
We have the following information:
Dave has one $20 bill, three $10 bills, and the same number of $5 bills and $1 bills in his pocket.
The number of $5 and $1 bills are n.
a) So, we will have the following expression for the total money he has:
1*20+3*10+5n+n
20+30+5n+n
Now, adding the numbers together and the terms with the same variable together:
$(6n+50)
b) Now, when n = 5:
$(6*5+50)
$(30+50)
$80
Hence, the simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.
