A snapdragon with pink flowers with the genotype Rr is mated with a snapdragon with red flowers with the genotype RR. What is the possibility of obtaining a flower with a heterozygous genotype? The possibility of obtaining a heterozygous flower is

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.
