The sample is his friends. They might be the same group of interests. The sample needs to be random.

Answer:
$535.25
Step-by-step explanation:
withdrawal means to take out (subtract)
$539.50- $35.50= $504
$504- 23.75= $480.25
deposit means to put in (addition)
$480.25+ $55.00 = $535.25
2+(-3) = -1
2- 3 = -1
-1=-1
The question is why though ?
It is because you keep the negative exponent which is with the biggest number. So this is how its look like +2 -3, so 3 is bigger then 2 so for that reason you keep the negative sign.
I hope that's help:)
