conversations.value: First we need to find the total amount for the robots. 7 robots * $8.75 per robot = $61.25 in total.
  Now we need to add in the tax $61.25 for the robots + $7.22 for tax = $68.47 total spent in store.
  Now to find what was the beginning amount we take the $68.47 total spent in-store + $11.53 in change = $80 to start.
