Answer:
A = $8406.6
Step-by-step explanation:
Given:
Average rate
Initial cost of painting
Time
We need to find the final amount of painting at the end of a 20-year.
Solution:
Using Exponential Growth rate formula as:
----------(1)
Where:
A = Final amount
a = Initial amount.
r = Rate as a decimal.
t = Time.
Now, we substitute all given values in equation 1.
Substitute in above equation.
A = $8406.62
Therefore, value of the painting at the end of a 20-year A = $8406.6
Ellie's age = 58 years
Genya's age = 2 years
Step-by-step explanation:
Let e represent Ellie's age
and
g be Genya's Age
Then
In six years
Ellie will be e+6 years old and Genya will be g+6 years old
then
Putting g= 8e+42 in equation 1
Dividing both sides by 9
Putting e = 2 in equation 1
Hence,
Ellie's age = 58 years
Genya's age = 2 years
