Answer:
Answer: 20 dollars
Step-by-step explanation:
Let Eli initial savings = X
Angela initial savings = Y
If Eli has saved $8 more than 1/3 of Angela's savings, then
X = 1/3Y + 8
X =( Y + 24)/3 ........ (1)
If they each save $10 more, Eli will have saved $4 more than Angela's savings. That is,
X + 10 = (Y + 10) + 4
Make Y the subject of formula
Y = X - 4 ......... (2)
Substitute Y in equation 1 into equation 2. Gives
X = ((X - 4) + 24) ÷ 3
3X = X + 20
2X = 20
X = 10 (That is the initial savings )
they each save $10 more. That is X + 10
Eli has therefore saved 20 dollars
