Answer:

Step-by-step explanation:
<h2>This account can be modeled using the compound interest formula.</h2><h2>the compound interest formula is expressed as</h2>

Where
A =final amount = y
P=initial principal balance
= $300
r=interest rate = 16%= 0.16
t=number of time periods elapsed= x
Hence the equation to model his account balance/ final amount A (y) after time (x) years is

31500 meters.
Step-by-step explanation:
3.5 km times 9 = 31.5 km
25.5 km = 31500 meters

Answer:
81.94.
45.82+100+100=245.82
245.82 divided by 3 is 81.94.
A. $1250; $1500 because if you bought something for $1250 and sold it for $1500 you would be gaining $250
First, we have to find the area of the wall, then the area of the window, then subtract them.
Area of wall = 9 × 9 = 81 sq.unit
Area of window = 3 × 3 = 9 sq.unit
So, the area of the wall ( excluding window ), = 81 - 9 = 72 sq. unit
