Answer 1

D: 1.05d

Explanation:

The price per pound last month = d dollars

The price increased by 5% this month compared to the price last month.

Therefore, the price this month will be:

`\begin{gathered} d+(5\%\text{ of }d)=d+0.05d \\ =(1+0.05)d \\ =1.05d \end{gathered}`

The expression that shows the price per pound of potatoes this month is 1.05d.

The correct option is D.
