  To find the original cost of the shirt

  Let the original cost be x

  The markup percentage is 25%, which means the store is selling the shirt for 100% + 25% = 125% of the original cost.
  So now the equation is
  x + 25% of x = $40

  We can write 25% as 0.25

  So, x + 0.25x = $40

  1.25x = $40

  x = $40 / 1.25

  x = $32

  Therefore, the original cost of the shirt was $32.

  So, the correct answer is option c)$32.
