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
