The Supplemental Security Income (SSI) program, administered by the Social Security Administration (SSA), is the income source of last resort for thelow-income aged, blind, and disabled. As the nation's largest income-assistance program, it paid $38 billion in benefits in calendar year 2006 to roughly 7 million recipients per month. BecauseSSI is means tested, administering the program often requires month-to-month, recipient-by-recipient benefit recomputations. An increase in a recipient's income usually triggers a benefit recomputation. Or, an increase in the recipient's financial assets, which may render the recipient ineligible, would also prompt a recomputation. With this crush of ongoing recomputations, it is of little wonder that administrative simplification is a time-honored mantra for program administrators.

Jess and Wes used to race each other when they were younger. Jess could cover 8
marshall27 [118]

Answer:

160 meters

Step-by-step explanation:

Let call dj  distance run by  Jess    and   dw  distance run by Wes

By Jess courtesy Wes will be  60 meters ahead of Jess

Let call t the time in which both runners are at the same point, which in fact is when both distances are equal

dj  =  8 m/sec * t        and    dw  =  60  +  5 m/sec * t

Then we make  dj = dw

8*t  =  60 + 5*t

3*t  =  60

t = 20 sec

Now passed 20 sec  dj   =   8 * 20   = 160 m

and   dw = 60 + 5*20   dw  =  160 m
