= 85d/100

= 0.85d.

Expression-2: total paid = 85% of d. or discount is 15% of d which is 0.15d. so total paid is d−0.15d

How did we arrive at these values?

B. This expression 0.90(d−5) refer to the total pay by Winona and Takoda if they want to buy their mother the jewelry

If you observe the table, there is the cost d-5 in jewelry.

And the discount is 10%. which is also represented as 10/100.

Therefore that total paid for jewelry becomes 0.90(d−5)

Other method:

Total paid = (d−5)−10% of d−5.

= (d−5)−(d−50)10/100

= (d−5)−(10d−50)/100

= 90d - 450/100

= 9d - 45/10

= 9(d-5)/10

= 0.90(d-5)

C. Let consider d =30.

1 total cost of power tools = 30

total paid of power tools = 0.85 (30)

= 25.5

2) Total cost of water skis = 30 + 15

= 45

Total paid water skis = 0.75(d+15)

= 0.75(45)

= 33.75

3) Total cost of jewelry = 30 − 5

=25⋅

Total paid of jewelry = 0.90 (25)

= 22.5

Based on the calculated amounts, Winona and Takoda should consider buying the jewelry as it has the lowest total cost among the three options. For d = 30, the total cost of jewelry is $22.50, making it the most budget-friendly choice.

Complete question:

Winona and Takoda are shopping for a present for their mother. The chart shows several possible presents. There is no sales tax in the state where they live. a. Write two expressions in terms of d to show how much Winona and Takoda would pay in total if they buy their mother the set of power tools. b. What does the expression 0.90(d-5) refer to? How do you know? How else could this expression be written? c. Choose a value for d that is greater than $25 and less than $100. Calculate the total cost of each of the possible presents for the value you chose. Then write a short paragraph telling Winona and Takoda which present they should buy and explaining why.
