Step-by-step explanation:
The complete question in the attached figure
Let
L ----> the length of rectangle
W ---> the width of rectangle
we know that
The perimeter of rectangle is equal to
In this problem we have
substitute the values
Simplify

Michelle didn't multiply the sum of length and width by 2
After 14 months after the first month would the sales reach $9000
For given question,
A Hammer Hardware has sales of $5000 in its first month.
The sales were to increase by 4% every month.
We need to find the number of months after the first month would the sales reach $9000
Let the exponential function for sales is,
f(n)= a (1 + r)^{n}
where, n is the number of months
a is the sales of the first month
r is the rate of increment
So, a = $5000, r = 0.04, f(n) = $9000
Substitute values in above equation.
⇒ 9000 = 5000 × (1 + 0.04)^{n}
Solve above equation for n.
⇒ 1.8 = (1.04)^n
⇒ n =
⇒ n = 14.9
⇒ n ≈ 15
Therefore, after 14 months after the first month would the sales reach $9000
