60,000
Step-by-step explanation:
Jane-2000
Peter-ratio of 5=25000
Marta-ratio of 7=35000
25000+35000
60000
Answer:
$6,000
Step-by-step explanation:
If [tex]y[/tex] is the amount of money a child receives, and [tex]x[/tex] is the total amount being divided among the children, then
Jane's share: [tex]y = \frac{4}{4+5+7} * x = \frac{4}{16}x[/tex]
Peter's share: [tex]y = \frac{5}{4+5+7} * x = \frac{5}{16}x[/tex]
Martha's share: [tex]y = \frac{7}{4+5+7} * x = \frac{7}{16}x[/tex]
We know Jane got $2000, so we can use that to solve for [tex]x[/tex]:
[tex]\frac{4}{16} x = 2000[/tex]
[tex]x = \frac{16}{4} * 2000 = 8000[/tex]
Plug this x value in to find how much Peter and Martha received:
[tex]\frac{5}{16} * 8000 + \frac{7}{16} * 8000 = $6000[/tex]
