When water is distilled, any solutes dissolved in the water are left behind. Is distilled water hypertonic or hypotonic compared to tap water? Explain.

Hypotonic

Explanation:

Tap water contains a lot of solutes and ions that are absent in distilled water. The solution that has more solutes (more dissolved solids) will be the hypertonic solution.

Here, distilled water has no solutes, making it hypotonic.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
