Short paragraph telling winona and takona which present they should buy
A. To calculate the total cost for Winona and Takona if they bought their mother the set of power tools, the expression would be 2d dollars.
B. The expression 0.90(d-5) refers to a discounted price for an item that originally cost d dollars. The 0.90 represents a 10% discount, and the (d-5) represents a $5 deduction from the original price. This expression could also be written as 0.90d - 4.50.
C. Let's choose d = $50.
For the power tools, the total cost would be 2 * $50 = $100.
For the water skis, the total cost would be ($50 + $15) = $65.
For the jewelry, the total cost would be ($50 - $15) = $35.
In this case, Winona and Takona should buy the jewelry as it is the least expensive option at only $35.
