Answer:
Option B is correct.
Step-by-step explanation:
CPI stands for Consumer Price index and is used to find the inflation.
The formula used to find CPI is
CPI = (Price of baskets of goods in one year/ Price of baskets of goods in base year) * 100
Here the base year is the starting year, in our case it is 1983 and price of can of paint is $16.35
So, CPI in 2000
Using the above formula and putting the values
CPI in 2000 = (28.94 / 16.35) * 100
CPI in 2000 = 177
CPI in 2005
Using the above formula and putting the values
CPI in 2005 = (32.54 / 16.35) * 100
CPI in 2005 = 199
Difference in CPI between 2000 and 2005 = CPI in 2005 - CPI in 2000
Difference in CPI between 2000 and 2005 = 199 - 177
Difference in CPI between 2000 and 2005 = 22
So, Option B is correct.
It has to be 80 as far as I know
Answer:
81 times the original size
Step-by-step explanation:
AA0ktA=3A0=?=?=25hours=A0ekt
Substitute the values in the formula.
3A0=A0ek⋅25
Solve for k. Divide each side by A0.
3A0A0=e25k
Take the natural log of each side.
ln3=lne25k
Use the power property.
ln3=25klne
Simplify.
ln3=25k
Divide each side by 25.
ln325=k
Approximate the answer.
k≈0.044
We use this rate of growth to predict the number of bacteria there will be in 100 hours.
AA0ktA=3A0=?=ln325=100hours=A0ekt
Substitute in the values.
A=A0eln325⋅100
Evaluate.
A=81A0
At this rate of growth, we can expect the population to be 81 times as large as the original population.
