Lyra bought a pair of shoes at a 20% discount. If she paid $480, how much was the original price of the pair of shoes?
Stream of thoughts:
600
Lyra only paid $480 for the pair of shoes which is only 100% - 20% = 80% of the original price.

So let x be the original price.

Then 0.

8x = $480.

Thus x = $480 / 0.

8 = $600.

.

Therefore, the answer is 600
