If Jess wants to increase her savings exponentially, which option(s) should she choose?
Only option 1, because it shows equal increases in equal intervals of time

Only option 2, because it shows equal increases in equal intervals of time

Either option 1 or option 3, because they show increases in time by the same percentages

Either option 2 or option 3, because they show increases in time by the same percentages

Choose the option, where every ratio of the next to the previous is the same.
