Answer:

  • Each stone sphere costs $43.64

Step-by-step explanation:

Let the cost of stone sphere is s and stone cylinder is c.

According to question we have equation:

  • 5s + 3c = 2s + 7c

Solve it for s:

  • 5s - 2s = 7c - 3c
  • 3s = 4c

Substitute the value of c:

  • 3s = 4*32.73
  • 3s = 130.92
  • s = 130.92/3
  • s = 43.64
