Answer:
Pierre is right
Step-by-step explanation:
The correct formula for Exponential growth rate is given as:
y = a( 1 + r) ^t
Where
y = Amount after time t
a = Initial amount
r = Growth rate
t = time
From the question
a = 300
r = 2% = 0.02
Hence, our exponential growth rate =
y = 300( 1 + 0.02)^t
y = 300( 1.02)^t
Therefore, Pierre is right
The value of when the value of is multiplied by is .
According to the statement, we have the following relationship:
(1)
Where:
- Independent variable.
- Dependent variable.
- Proportionality constant.
We can eliminate the proportionality constant by constructing the following relationship:
If we know that , , and , then the value of when the value of is multiplied by is:
Therefore,
Given:
To Find:
a₂₁ = ?
Solution:
Let,
We require ' a₂₁ ' i.e Second Row First Column Element
So on Comparing we get
∴
5%
22.05-21=1.05
1.05/21=.05
.05*100=5%
5 bags of popcorn and 6 candies.
(5 * $5.50) + ($3.5*6) = $48.5
