d+0.05d

d−0.05d

d+1.05d

d−1.05d

Answer 1

To calculate the total cost of the shirt, including a 5% sales tax, we can break it down as follows:

1. The cost of the shirt is \( d \).
2. The sales tax is 5% of \( d \), which is \( 0.05d \).

Therefore, the total cost of the shirt including the tax can be summarized as:
\[
\text{Total cost} = d + 0.05d
\]

This simplifies to:
\[
\text{Total cost} = 1d + 0.05d = 1.05d
\]

So the expression that can also represent the total cost of the shirt, including a sales tax of 5%, is:
\[
d + 0.05d
\]

Thus, the correct answer is:
**d + 0.05d**.
