Final answer:
The area, B, of a sheet of paper originally measuring 200 square inches, after being folded into thirds n times, is described by the equation B = 200 × (1/3)^n.
Step-by-step explanation:
To find the equation that represents the area, B, of a sheet of paper after being folded into thirds n times, we need to recognize that each fold reduces the area of the paper by a factor of 3. Since the area of the paper is initially 200 square inches, folding it n times means dividing the area by 3, n times.
The equation is:
B = 200 × (⅓)^n
Where B is the final area in square inches, and n is the number of times the paper is folded into thirds.
