70% off means she only paid 30% so if x = original price,
54/x = 30/100.
Cross multiply
30x = 5400 so divide by 30
x = $180

The original price of the item is 180

The given expression:

The final amount  paid by Joyce after the discount = 54.00

the given discount = 70 %

To find:

  • the original price of the item.

Let the original price of the item = y

The original price of the item is calculated as follows:

[tex]100\% \ y \ - \ 70\% \ y = 54\\\\30\% \ y = 54\\\\0.3 y = 54\\\\y = \frac{54}{0.3} \\\\y = 180[/tex]

Thus, the original price of the item is 180
