Explanation:
Adam purchased a furniture which was 25% off than the actual amount, that is, $820, which is the original price. Now in order to know the amount of money Adam saved, we need to make a calculation. For that, we need to divide 25 by 100 and multiply it with $820.
[tex]\frac{25}{100} \times 820 = 205[/tex]
The amount of money Adam saved is $205.
