Answer:
39.95 + 1.99x Option D.
Explanation:
Sara bought shoes costs = $39.95
and x pairs of socks costs = $1.99 each
To calculate the total money that Sara spent we will multiply x by $1.99 and add it to the cost of shoes that is $39.95.
the expression will be
39.95 + 1.99x
Option D will be the answer.
