a. Write two expressions in terms of d to show how much Winona and Takada will pay in total if they buy their mother the set of power tools.

Answer 1

To write the expressions, let's define the costs based on \(d\):

1. Let \(d\) represent the amount each of them pays for the power tools.
2. If Winona pays \(d\) and Takada also pays \(d\), then their total payment can be expressed as the sum of their individual payments.

Thus, the total amount they will pay in terms of \(d\) can be expressed as:

Expression 1: \(T = d + d\)

Expression 2: \(T = 2d\)

Both expressions show that the total amount they will pay for the set of power tools is \(2d\).
