First we need to find the total amount for the robots. 7 robots * $8.75 per robot = $<<7*8.75=61.25>>61.25 in total.
Now we need to add in the tax $61.25 for the robots + $7.22 for tax = $<<61.25+7.22=68.47>>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 = $<<68.47+11.53=80>>80 to start.
#### 80
