the usual price of a bar of chocolate cost $6,buy one bar of chocolate at 10% discount. If Jojo bought a bar of chocolate at the sale. How much did she pay?

1. Break Down the Problem

To find out how much Jojo paid for the chocolate bar after the discount, we need to:

1. Calculate the amount of the discount.
2. Subtract the discount from the original price.

2. Relevant Concepts

The formula for calculating the discount is: $\text{Discount} = \text{Original Price} \times \left(\frac{\text{Discount Percentage}}{100}\right)$ Then, the final price after discount can be calculated as: $\text{Final Price} = \text{Original Price} - \text{Discount}$

3. Analysis and Detail

1. Original Price: $\$6$
2. Discount Percentage: $10\%$

Calculating the Discount: $\text{Discount} = 6 \times \left(\frac{10}{100}\right) = 6 \times 0.1 = 0.6$

Calculating the Final Price: $\text{Final Price} = 6 - 0.6 = 5.4$

4. Verify and Summarize

Jojo receives a discount of $0.60 on the original price. Therefore, the price she paid after the discount is $5.40.

Final Answer

Jojo paid $5.40 for the bar of chocolate after the discount.
