Area = 152ft²
Step-by-step explanation:
Simpifly:
A = 13(13-6) + 9(13-6)
A = 13(7) + 9(7)
A = 22(7)
A = 22(7)
A = 20(7)+2(7)
A = 140 + 14
A = 152

Answer:
The amount of money is 60$
Step-by-step explanation:
Given, Principal, P = $40
Rate, R = 10%

= 20 + 40 = 60$
Answer:
Therefore there were 43,872 cell phone subscribers in Centerville in 1994.
Step-by-step explanation:
Given that, in 1985 , the number of cell phone sub subscribers was 285 in the small town Centerville.

The number of subscribers increased per year, to find the number of subscriber we have to use compound formula.
Here A = ?
P= 285
r= 75%
n=(1994-1985) year= 9 year
≈43,872
Therefore there were 43,872 cell phone subscribers in Centerville in 1994.
