Answer:

$14.12 (after 3 years) and $24.62 (after 5 years)

Step-by-step explanation:

Use the compound amount formula (assuming annual compounding):

A = P(1 + r)^t

Here A = $100(1 + 0.045)^3 (after 3 years)

= $100(1.045)^3 = $114.12.

The interest earned (alone) would be $14.12.

After 5 years:

Here A = $100(1 + 0.045)^5 (after 5 years)

= $100(1.045)^5 = $124.62

The interest earned (alone) would be $24.62.

Step-by-step explanation:

based on the story told I expected completely different questions.

but for the actually asked question the whole thing about gaining our not gaining weight is competent irrelevant. ignore it.

so, all we need to do is looking at the row totals.

27.4% of the participants took 1 vitamin.

49.5% of the participants took more than 1 vitamin.

so, 49.5% + 27.4% = 76.9% of all participants are taking vitamins in some form.

therefore, the second answer option is correct.
