Answer: the number of years is 7.3 years
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^ t
Where
A represents the population after t years.
t represents the number of years.
P represents the initial population.
r represents rate of growth.
From the information given,
P = 1250
A = 1000
r = 3% = 3/100 = 0.03,
Therefore
1000 = 1250(1 - 0.03)^t
1000/1250 = (0.97)^t
0.8 = 0.97^t
Taking log of both sides, it becomes
Log 0.8 = tLog 0.97
- 0.0969 = - 0.0132t
t = - 0.0969/- 0.0132t
t = 7.3 years
I do believe it might be the first option.
Answer:
Step-by-step explanation:
Total amount = 4.95
Per pound of banana = 0.59
Total amount of banana = 0.59 x 3 = 1.77
Remaining amount = 4.95 - 1.77 = 3.18
Cost of per pound of apple = 3.18 ÷ 2 = 1.59
B because it takes 1 hour to complete 3/4 of a page so 3/3 = 1 hour 1 1/3 =1 and a third of an hour
D because the insurance pays out a sum of money after death or a set period
