Question

A book was on sale for $40 straight percent sign$ off its original price. If the sale price of the book was $straight $ 18.00 comma$ , what was the original price of the book? (Assume there is no sales .)

$$ 7.20$
$$ 10.80$
$$ 30.00$
$$ 45.00$

hint Hint:

Hint:

A percentage is a numeral or ratio that can be defined as a fraction of 100

The correct answer is: $straight $ 30.00$

Explanation:

We have given a book was on sale for $40 straight percent sign$ off its original price. If the sale price of the book was $straight $ 18.00$ Step 1 of 1:
Let the actual price of the book be x

Since the book is to be sold for off its original price, the actual cost of the book is

$x cross times left parenthesis 100 minus 40 right parenthesis straight percent sign$
$x cross times 60 straight percent sign$
0.6x
Therefore,
0.6x =18
x=30
Hence, Option C is correct.
