Answer:

Not "free". The new sales price is $31.08

Step-by-step explanation:

Given that the costs of the drone ($129.50) is discounted 40%, the new price after the discount

= $129.50 - 40% * $129.50

= $129.50 - $51.80

= $77.70

Given that the  next month, the sale price is discounted an additional 60%., the new price after this discount

= $77.70 - 60% * $77.70

= $77.70 - $46.62

= $31.08

From above, the drone is not "free". The new sales price is $31.08
