Let's break down both parts of your question:
2a.
The expression for the total cost if Winonna and Takoda bought the set of power tools, with a discount of 15%, would be:
Correct Response: \[ d - (d \times 0.15) \]
This expression indicates you take the original price \( d \) and subtract 15% of that price.
2b.
Next, we need to calculate the sales prices for each present using the original price of the power tools, which is $50.00. Let’s perform the calculations based on the discount percentages you mentioned (assuming the percentage information was given in the chart, which should typically look like this):
-
Power Tools: 15% discount \[ \text{Discount} = 50 \times 0.15 = 7.50 \] \[ \text{Sales Price} = 50 - 7.50 = 42.50 \]
-
Water Skis: (Assume a certain discount percentage, e.g., 20%) Let’s say the original price is $100. If we assume a 20% discount: \[ \text{Discount} = 100 \times 0.20 = 20.00 \] \[ \text{Sales Price} = 100 - 20 = 80.00 \]
-
Jewelry: (Assume a certain discount percentage, e.g., 10%) If we assume an original price of $200 with a 10% discount: \[ \text{Discount} = 200 \times 0.10 = 20.00 \] \[ \text{Sales Price} = 200 - 20 = 180.00 \]
Now you can drag the calculated sales prices to the correct present based on the price you calculated for each item.
If discounts for water skis and jewelry were provided in the chart, adapt the calculations accordingly to get the correct sales prices for those items.
