If the proportion of iris to roses in Nikki's garden is 2: 5, it means that for 25 roses: (2/5) = (10/25). Therefore to maintain the proportion by adding 20 roses: (2/5) = (18/45). The number of irises after the addition of roses will be 10 + 18 = 28 irises.
Answer:
5.19%
Step-by-step explanation:
The amount of an account (A) earning simple interest rate r for time t on principal P is ...
A = P(1 +rt)
Filling in the given values and solving for r gives ...
6000 = 5500(1 +r(21/12))
12/11 = 1 + r(7/4) . . . . . . . . . . divide by 5500, simplify fractions
1/11 = r(7/4) . . . . . . . . subtract 1
4/77 = r . . . . . . . . . . . multiply by 4/7
r ≈ 0.051948 ≈ 5.19%
You will be earning about 5.19% annual simple interest.
