To solve the problem, we need to calculate the discount sale price for each item based on the given original price and the discount percentage. The formula to calculate the discount sale price is:
\[
\text{Discount Sale Price} = \text{Original Price} - (\text{Original Price} \times \text{Discount Percentage})
\]
Alternatively, we can use:
\[
\text{Discount Sale Price} = \text{Original Price} \times (1 - \text{Discount Percentage})
\]
Let's solve each part step by step.
---
1. If an item has an Original Price of $212$, then it may be discounted by $39\%$. Then, My Discount Sale Price is:
-
Original Price = $212$
-
Discount Percentage = $39\% = 0.39$
Using the formula:
\[
\text{Discount Sale Price} = \text{Original Price} \times (1 - \text{Discount Percentage})
\]
\[
\text{Discount Sale Price} = 212 \times (1 - 0.39)
\]
\[
\text{Discount Sale Price} = 212 \times 0.61
\]
\[
\text{Discount Sale Price} = 129.32
\]
So, the discount sale price is
$129.32.

2. If an item has an Original Price of $812$, then it may be discounted by $13\%$. Then, My Discount Sale Price is:
-
Original Price = $812$
-
Discount Percentage = $13\% = 0.13$
Using the formula:
\[
\text{Discount Sale Price} = \text{Original Price} \times (1 - \text{Discount Percentage})
\]
\[
\text{Discount Sale Price} = 812 \times (1 - 0.13)
\]
\[
\text{Discount Sale Price} = 812 \times 0.87
\]
\[
\text{Discount Sale Price} = 705.24
\]
So, the discount sale price is
$705.24.

3. If an item has an Original Price of $111$, then it may be discounted by $49\%$. Then, My Discount Sale Price is:
-
Original Price = $111$
-
Discount Percentage = $49\% = 0.49$
Using the formula:
\[
\text{Discount Sale Price} = \text{Original Price} \times (1 - \text{Discount Percentage})
\]
\[
\text{Discount Sale Price} = 111 \times (1 - 0.49)
\]
\[
\text{Discount Sale Price} = 111 \times 0.51
\]
\[
\text{Discount Sale Price} = 56.61
\]
So, the discount sale price is
$56.61.

4. If an item has an Original Price of $291$, then it may be discounted by $19\%$. Then, My Discount Sale Price is:
-
Original Price = $291$
-
Discount Percentage = $19\% = 0.19$
Using the formula:
\[
\text{Discount Sale Price} = \text{Original Price} \times (1 - \text{Discount Percentage})
\]
\[
\text{Discount Sale Price} = 291 \times (1 - 0.19)
\]
\[
\text{Discount Sale Price} = 291 \times 0.81
\]
\[
\text{Discount Sale Price} = 235.71
\]
So, the discount sale price is
$235.71.
---
5. If an item has an Original Price of $315$, then it may be discounted by $29\%$. Then, My Discount Sale Price is:
-
Original Price = $315$
-
Discount Percentage = $29\% = 0.29$
Using the formula:
\[
\text{Discount Sale Price} = \text{Original Price} \times (1 - \text{Discount Percentage})
\]
\[
\text{Discount Sale Price} = 315 \times (1 - 0.29)
\]
\[
\text{Discount Sale Price} = 315 \times 0.71
\]
\[
\text{Discount Sale Price} = 223.65
\]
So, the discount sale price is
$223.65.
