Answer:
They have 62 cookies left
Step-by-step explanation:
6 X 15 = 90
90 - 28 = 62
Answer:
so you use the formula:
A = P(1 + r/n)nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
and you will get:
A = $ 4,432.85
A = P + I where
P (principal) = $ 3,600.00
I (interest) = $ 832.85
To find the population after a year, you can multiply 4.5x10⁸ by 1.05, as it increases by 5% per year (1.05=1+5%). To find the population after five years, you have to multiply 4.5x10⁸ by 1.05 five times.
4.5x10⁸(1.05)⁵
=574326703.125
Since you can't have a decimal amount of people, you round this number to 574326703.
Therefore, the population after five years is going to be about 574326703.
918.642 x 1/10 = 918.642 x 0.1 = 91.8642
