Question 64726
I believe the answer is {{{abs(250-d)<5}}}
Suppose the money in the account is $254.99
{{{abs(250 - 254.99) < 5}}}
{{{abs(-4.99) < 5}}}
This is true. If there were one more penny 
in the account, it would be false.
Suppose the money in the account is $245.01
{{{abs(250 - 245.01) < 5}}}
{{{abs(4.99) < 5}}}
This is true
If there were one penny less in the account,
it would be false,
so {{{245.01 <= d <= 254.99}}} is another way to state it.
