Answer:
The amount that William has at the beginning is $37.50 and the amount that Gracie has at the beginning is $52.50
Step-by-step explanation:
Let
x ---> amount that William has at the beginning
y ---> amount that Gracie has at the beginning
we know that
William says to Gracie, "If you give me $7.50,we will have and equal amount of money
so

----> equation A
"Grace responds, if you give me $ 7.50 instead, I will have twice as much money as you


----> equation B
substitute equation A in equation B

solve for x

Find the value of y

therefore
The amount that William has at the beginning is $37.50 and the amount that Gracie has at the beginning is $52.50
The first question is this: the smallest square is square A, and that is 9 units. and square E is two times that, and so on.
Square A's side length is 9 units and the area is 81.
Square E's side length is 18 and the area is 324.
Square C's side length is 27 and the area is 729.
Square B's side length is 36 and the area is 1,296.
Square D's side length is 45 and the area is 2,025
