It would have to be the first option.
The second option is not correct because you are not adding more than what her goal is.
The third option is not correct because you are not dividing from her goal.
The fourth option is not correct because it would ultimately result in a negative number.
The first option is correct because it subtracts how many days she has ran times 5 from her goal. The resulting answer would show how many miles she has left to reach her goal of 100 miles during that month.
Hope this helps!
