Answer:

$6,000

Step-by-step explanation:

If y is the amount of money a child receives, and x is the total amount being divided among the children, then

Jane's share:  y = \frac{4}{4+5+7} * x = \frac{4}{16}x

Peter's share:  y = \frac{5}{4+5+7} * x = \frac{5}{16}x

Martha's share:  y = \frac{7}{4+5+7} * x = \frac{7}{16}x

We know Jane got $2000, so we can use that to solve for x:

\frac{4}{16} x = 2000

x = \frac{16}{4} * 2000 = 8000

Plug this x value in to find how much Peter and Martha received:

\frac{5}{16} * 8000 + \frac{7}{16} * 8000 = $6000
