Answer:
The oldest gets -> $335,500
The middle gets -> $182,750
The youngest gets -> $167,750
Step-by-step explanation:
Step 1: Make an equation
686,000 = 2y + (15,000 + y) + y
Step 2: Solve for y
686,000 - 15,000 = 2y + 15,000 + y + y - 15,000
671000 / 4 = 4y / 4
167,750 = y
Step 3: Figure the amount of money the middle sibling gets
m = y + 15,000
m = 167,750 + 15,000
m = 182,750
Step 4: Figure the amount of money the oldest sibling gets
o = 2y
o = 2(167,750)
o = 335,500
Answer: The oldest gets -> $335,500
The middle gets -> $182,750
The youngest gets -> $167,750
Answer:
$335,500
$182,750
$167,750
Step-by-step explanation:
Let the amount received by the eldest sibling be A , the middle sibling be B and the youngest sibling be C.
Given
The eldest A received two times as the youngest C.
That’s
A = 2C
Also,the middle sibling received $15000 more than the youngest .
That’s
B = C + $15000
Therefore,
A + B + C = $686000
We now have three expressions
A = 2C
B = C + 15000
A + B + C = 686000
Substitute the first two expressions or values of A and B into the third expression
We have
2C + C + 15000 + C =686000
Rearrange the expression as
2C + C + C + 15000 =
4C + 15000 = 686000
Subtract 15000 from both sides
4C + 15000 - 15000 = 686000 - 15000
4C = 671000
Divide both sides by by 4
C = 671000/4
C = 167750
C = $167,750
The youngest sibling received $167,750
Recall,
A = 2C
Therefore
A = 2 x $167,750
A = $335,500
The eldest sibling received
$335,500
Also,
B = C + $15000
B = $167,750 + $15000
B = $182,750
The middle sibling received $182,750
The eldest sibling received $335,500
The middle sibling received $192,750 and
The youngest sibling received $167,750
