Marissa is walking along the beach and finds an unknown organism on the shore. it has bilateral symmetry, a nongelatinous, nonsegmented body that is bigger than 0.5 mm, and a shell. in which phylum can the organism be classified?

9.9 years

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.

ya the other dude is right
