100% + 30% = 130%
130% x = 520 Change a % to a decimal
(130/100) x = 520
1.3 x = 520 Divide by 1.3
x =520 / 1.3
x = 400 

So the original cost of the item was 400 dollars.

Answer:

Original price was $400.

Step-by-step explanation:

Let the original price = x dollars.

It is given that the new price is obtained by increasing the original price by 30% i.e. 0.3

As, the new price is $520.

So, we have the relation,

[tex]x+0.03x=520[/tex]

i.e. [tex]1.3x=520[/tex]

i.e. [tex]x=\frac{520}{1.3}[/tex]

i.e. x = 400

Hence, the original price was $400.
