Answer:
Option A. $103.
Step-by-step explanation:
A new pair of sneakers cost $70 now.
The cost of the shoes after 5 years if the price increases 8% per year.
We will solve it by this formula
Where A = final amount after t years
r = rate of increase
n = compounded in a year
t = time in years
A = 70(1.08)⁵
A = 70 × 1.46932808
A = 102.8529 ≈ $103
Option A $103 is the answer.

The area of the inner square to the area of the outer square ratio is:
Given a figure in which an inner square is inscribed inside the outer square.
The area of a square is the product of the two sides of the square. Also known as side square.
Firstly, we will find the side of the inner square by finding the distance between the points (0,b) and (a-b,0)
S₁=√(a-b-0)²+(b-0)²
S₁=√(a-b)²+b²
Now, we will find the area of the inner square, we get
The area of the inner square=(side)²
A₁=(S₁)²
A₁=(√(a-b)²+b²)²
A₁=(a-b)²+b²square cm.
Further, we will find the side of the outer square by finding the distance between the points (0,0) and (a,0).
S₂=√(a-0)²+0²
S₂=√a²
S₂=a
Furthermore, we will find the area of the outer square, we get
The area of the outer square=(side)²
A₂=(S₂)²
A₂=a² square cm.
Hence, the area of the inner square to the area of the outer square ratio is .
