This problem is about percentages.

We know that Jack's health plan decreased from $325 to $115.

To find the percentage that represents this decreased, we just need to divide the least numbers by the greater number

[tex]\frac{115}{325}=0.35[/tex]

Then, we multiply this result by 100, to get it in percentage

[tex]0.35\cdot100=35[/tex]

Therefore, the right answer is 35%.
