Answer:
The answer to your question is: One has saved $35 and the other $20
Step-by-step explanation:
Data
2 brothers
combined savings = $55
One brother has $15 more than the other
x = savings of one brother
y = savings of the other brother
- Process
Write an equation or two equations and solve it for x and y
(1) x + y = 55
(2) x = y + 15 Solve this system by substitution (2) in (1)
y + 15 + y = 55
2y = 55 - 15
2y = 40
y = 40/2
y = $ 20
x = 20 + 15
x = $ 35
