Answer: 39 dollars
===================================================
Step-by-step explanation:
The price drops by 35%, so it keeps the remaining 65% (since 100-35 = 65)
65% of $60 = 0.65*60 = 39 dollars
-------
A slightly longer method:
35% of 60 = 0.35*60 = 21
You save $21 and the final price is 60-21 = 39 dollars
