To solve the questions, let's break them down step by step.
Question 2a
We want to write an expression in terms of \( d \) to show the total cost if Winonna and Takoda buy the set of power tools. Since there is a discount of 15%, we need to find what 15% of \( d \) is and then subtract that from \( d \).
The discount amount is given by:
\[ d \times 0.15 \]
The total cost after discount can be represented as:
\[ d - (d \times 0.15) \]
So the correct expression is:
d - (d x 0.15)
Question 2b
Given \( d = 50 \) (the original price of the power tools), we will calculate the sales price for each present using their respective discount percentages. First, we need to establish the final prices based on those discounts.
-
Power tools: 15% discount
\[ \text{Discount} = 50 \times 0.15 = 7.50 \] \[ \text{Sales Price} = 50 - 7.50 = 42.50 \] -
Water skis: 20% discount
\[ \text{Discount} = 50 \times 0.20 = 10.00 \] \[ \text{Sales Price} = 50 - 10.00 = 40.00 \] -
Jewelry: 10% discount
\[ \text{Discount} = 50 \times 0.10 = 5.00 \] \[ \text{Sales Price} = 50 - 5.00 = 45.00 \]
Now we can summarize the sales prices for each present:
- Sales price of the POWER TOOLS: $42.50
- Sales price of the WATER SKIS: $40.00
- Sales price of the JEWELRY: $45.00
You can drag and drop these responses into the correct inputs based on their corresponding presents.
