Answer:

Mother = 30\ years

Son = 10\ years

Step-by-step explanation:

Given

M = Mother

S = Son

From the first statement:

M = 3S

From the second:

M - S = 20

Required

Find M and S

We have:

M = 3S and

M - S = 20

Substitute M = 3S in M - S = 20

3S -S =20

2S = 20

Divide both sides by 2

S = 10

Substitute S = 10 in M = 3S

M = 3 * 10

M = 3 0

Hence;

Mother = 30\ years

Son = 10\ years

<h3>Answer: Choice (a)  $1,653.66</h3>

=====================================================

Work Shown:

Use the compound interest formula

A = P*(1+r/n)^(n*t)

A = 10000(1+0.039/1)^(1*4)

A = 11,653.65589441

A = 11,653.66

That's the amount of money Tammy will have at the end of 4 years.

Subtract off the principal from this value to get the interest.

interest = A - P

interest = 11,653.66 - 10,000

interest = 1,653.66
