After taking 20% off the original price, Victor paid $14 for a book. What was the original price of the book? My guess is 16.8 it is not a Q&A it is write your own please help.
Is it 17.5?
I mean it is 17.5.
Yes. The original price of the book was $17.50.
No. Why did you guess?
0.8x = 14
x = ?
To find the original price of the book, we can use the fact that Victor paid $14 after a discount of 20% was applied.
Let's denote the original price of the book as 'x'. We know that after taking 20% off the original price, Victor paid $14.
To find the price after the discount, we can subtract 20% (or 0.20) of the original price from the original price:
Price after discount = x - 0.20x = 0.80x
Since Victor paid $14, we can set up the equation:
0.80x = $14
Solving the equation, we divide both sides by 0.80:
x = $14 / 0.80
x = $17.50
Therefore, the original price of the book was $17.50. Your guess of $16.80 was close, but not quite correct.
