d+0.05d
d plus 0 point 0 5 d

d−0.05d
d minus 0 point 0 5 d

d+1.05d
d plus 1 point 0 5 d

d−1.05d

Answer 1

The total cost of the shirt, including a sales tax of 5%, can be represented by the expression \(1.05d\). This can also be expressed as:

\[ d + 0.05d \]

This is because \(0.05d\) represents the 5% sales tax added to the original cost \(d\).

So the correct response is:

d + 0.05d
