Answer:
years = natural log (total / principal) / rate
years = natural log (18,400 / 9,200) / 10
years = natural log (2) / 10
years = 0.69314718056 / 10
years = 6.9314718056
and this would be the time for ANY amount of money to double.
Step-by-step explanation:
Jack has 28 cards.
To double 14, multiply 14 times 2. 14x2=28
250 Rs.
600 / 12 x 5 = 250 Rs.
Ram will get 250 Rs.
At the end of two years Mrs.Scott earned $1929.36 (i rounded the dec.)
A= p(1+r)^t
P= 1750
r= .05
t= 2
A= 1750(1+.05)^2
A= 1929.375
$ 1.725
4 Pack of coffee = $ 6.90
1 Pack of coffee = $ 6.90 / 4 = $ 1.725( The word per means " 1 " )
