Question

Casey paid $32 for a book that was on a sale at 20% off. What was the original price for that book?

Answer 1

Step-by-step explanation:

Explanation:

(320) / (0.8) = 400. The couch has been marked down an additional 40% from the sale price of $320. $320 * 0.6 = $192. $400 – $192 = $208.

Answer 2

Given:

We have given Casey paid $32 for a book that was on a sale at 20% off.

To Find:

We have to find the original price for that book?

Step-by-step explanation:

• Let the original price of the book be rupees x.
• Casey paid for the book is $32.
• Discount on the original price is given to the Casey which is 20%.

        $20\%of x=\frac{20}{100} x$

• Now the amount that Casey paid is equal to the original price minus by the discount given to Cassey. hence, we can write it as.

        $x-\frac{20}{100}x =32$

• Now simply the left-hand side of the equation by taking the lL.C.M and subtracting the values.

       $\frac{100x-20x}{100} =32$

• Simplify the left-hand side of the above equation then crosse- multiply the terms.

        $\frac{80x}{100} =32\\80x=32\times100\\x=\frac{3200}{80} =40$

Hence, the original price of the book is 40$.
