Answer
The original price of the drill was 50 dollars.
Work Step by Step
Let s represent the original price.
We can use the following guideline to solve this problem.
Original selling price - Discount = Discount sale price
s - 30% $\times$ s = 35
s - 0.3s = 35
0.7s = 35
Divide both sides by 0.7:
s = 50
The original price of the drill was 50 dollars.
