We can write a proportion. We know that $420 is 70% of an unknown original price. Let's call it x. We write equal ratios of  comparing percent and  comparing the $420 to the original price. We then set them equal.

We then cross multiply across the equal sign from numerator to the opposite numerator.

70(x)=420(100)

70x=42000

We divide to find x.

x=600.
