Answer:
B.) 468.50
Explanation:
Mary will receive 50% of what Tim receives. The 100% is $937, to calculate the 50% we have to divide $937 by half (because 50% = 50/100 = 1/2).
$937/2 = $468.50
Mary will receive $468.50.
We are assuming that she doesn't receive social security benefits on her own, she just have the wife's benefit of 50% of Tim's benefit.
