900 - 60n ≥ 450
n ≤ 7.5
Answer: 7 weeks

Let n = numberof weeks.
In n weeks, you withdraw 60n from the account.
After withdrawing $60 for n weeks, teh amount must be at least $450. At least $450 means greater than or equal to $450.
900 - 60n ≥ 450
-60n ≥ -450
n ≤ 7.5

Answer
Are of the pool = w² + 5w (in square feet)
Explanation
Since the pool is rectangular in shape,
Area of the pool can be calculated using the formula for the area of a rectangle
Area of rectangle = length x width
Given,
Width of pool (Assume is same as height) = w
Length of pool= w + 5
Area = w * (w + 5)
= w² + 5w (in square feet)
where w is the width of the pool
