Oxana [17]

Answer:

3/5

Step-by-step explanation:

avg in A = 41

avg in B = 38

combined avg of A and B = 36

Let a = number of people in group A.

Let b = number of people in group B.

The total number of people = a + b.

The sum of all ages in group A is 41a.

The sum of all ages in group B is 36b.

The sum of all ages in the combined group A and B is 38(a + b).

41a + 36b = 38(a + b)

41a + 36b = 38a + 38b

3a = 2b

a/b = 2/3

a/b + 1 = 2/3 + 1

a/b + b/b = 2/3 + 3/3

(a + b)/b = 5/3

b/(a + b) = 3/5

Mrac [35]
You can use the simple interest formula 
P = irt

We need P, which is the primary (or principal) investment, and we know that:

rate = 3% (0.03)
time = 7
i = $25000

So, just plug in and solve:
I = 25000(0.03)(7)
I = 5250

The company needs to invest $5250 today, to make $25000 in 7 years.
