Answer:
3,063
Step-by-step explanation:
To find the population in a future year, use the formula:
where A is the amount, p is the starting population, r is 2.2% or 0.022, and t is the number of years after 2016.
Since the population is decreasing it is subtraction. Here we are finding A, P =3500, r=0.022, and t=6.
Answer:
Principal=P=24,000
Rate of interest=r=15%
Time=n=2

Here first we take n=2years
A=P(1+

where A=Amount and n=number of years

The amount after 2 years is Rs31,740
Now principal=Rs.31,740

year= Rs.31740+1587= Rs.33,327
C.I =A−P
∴C.I=33,327−24,000=Rs.9,327
19x + 119
Step 1. 42 goes into (x) making it 19(42) + 119
Step 2. solve (19 × 42 = 798) 798 + 199 = 997
so the total cost is 997
