Answer:

  • B. $320

Step-by-step explanation:

  • Initial amount that was received from the garage sale = x
  • Spent on bicycle = 1/2x
  • Spent on portable stereo set = 1/2(1/2x) = 1/4x

Money left:

  • 1/2x - 1/4x = 80
  • 1/4x = 80
  • x = 4*80
  • x = 320

Initial amount was $320

Correct choice is B
