Nice question!
This is especially GRE-worthy because, although it looks like we need to perform some long calculations, we can actually solve it using some estimation.

First recognize that a 60% off sale means the sale price is less than half of the original price

Now let's test some possible values for the original price.
If the original price were $300, then the sale price would be less than $150 (after the 60% price reduction).
However, we're told that the sale price must be $179.95
So, the original price must be greater than $300
Only one answer choice meets that condition.

Answer: E

Cheers,
Brent

We can let this weeks price = n and create the equation:

n - 0.6n = 179.95

0.4n = 179.95

n = 449.875

Rounding n up to the nearest hundredth, we obtain $449.88.

Answer: E
