Answer:
251$
Step-by-step explanation:
Let's say x represents Joes's account.
And y represents Chandra.
Since Joses account was 1 more than one half of chandra, the amount for Joes would be x = 1/2*y + 1
Now we can just say y = Chandra's amount.
So x + y = 751
And x = 1/2*y + 1
We have a systems of equation, and just plug in 1/2*y + 1 for x.
1/2*y + 1 + y = 751
1/2*y + y = 750 (subtract both sides by 1)
distribute y so...
y(1/2 + 1) = 750
y = 750/1.5
y = 500
Remember, y is Chandra. So plug in 500 for y in Joses equation, so 1/2(500) +
is 250 +1 so 251.
