What is the final price of a stereo originally costing $125 after a 20% discount?

• A. $105
• B. $100
• C. $120
• D. $90

Answer: (B)

To determine the final price of the stereo after applying a 20% discount to the original price of $125, it is essential to first calculate the amount of the discount. The discount can be calculated by multiplying the original price by the discount rate: \[ \text{Discount} = \text{Original Price} \times \text{Discount Rate} \] \[ \text{Discount} = 125 \times 0.20 = 25 \] Next, you subtract the discount from the original price to find the final price: \[ \text{Final Price} = \text{Original Price} - \text{Discount} \] \[ \text{Final Price} = 125 - 25 = 100 \] This calculation shows that after a 20% discount, the final price of the stereo is indeed $100.

To determine the final price of the stereo after applying a 20% discount to the original price of $125, it is essential to first calculate the amount of the discount.

The discount can be calculated by multiplying the original price by the discount rate:

[

\text{Discount} = \text{Original Price} \times \text{Discount Rate}

]

[

\text{Discount} = 125 \times 0.20 = 25

]

Next, you subtract the discount from the original price to find the final price:

[

\text{Final Price} = \text{Original Price} - \text{Discount}

]

[

\text{Final Price} = 125 - 25 = 100

]

This calculation shows that after a 20% discount, the final price of the stereo is indeed $100.
