Question 89815
Start by thinking of it this way ... ask yourself what was the total cost of everything
new that they bought. It was:
.
Television ............ $2110.00
TV Stand .............. $ 394.96
Pwr Surge & cables .... $ 115.00
.
The total cost to Debbie and Norris was the sum of these three expenditures which was $2619.96
.
Presume that they were to split this cost evenly with Debbie to pay half and Norris to
pay the other half. Then Norris should be expected to be out half of $2619.96 which is $1309.98
.
What has Norris paid out so far? He gave Debbie $750.00 and he bought the TV stand for $394.96
plus he paid $115.00 for a power surge surpressor and cables.  So Norris has paid out
the sum of these three or $750.00 + $394.96 + $115.00 which is a total of $1259.96.
.
But recall that we said he should spend $1309.96. Therefore, he owed Debbie the difference
between $1309.98 and the $1259.96 he has paid out so far.  Therefore, he owes Debbie
$1309.98 - $1259.96 = $50.02.
.
Hope this shows you a train of thought that you can use to come up with an answer to this 
problem.
