Question

What was the original price if:
a
after increasing by 30% it became $520?

Answer 1

Original price was $400.

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,

`x+0.03x=520`

i.e.
`1.3x=520`

i.e.
`x=(520)/(1.3)`

i.e. x = 400

Hence, the original price was $400.

Answer 2

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.
