Not exactly huge news and not exactly a lot of money either:
Here in Illinois a Single Mother with One Child Making $10/hour at full-time and getting child support of $500/month earns $2100/month gross
With rent of $750/month, taking $250/month out for dependent care and paying one utility that's not Heat/AC/Phone grants the Standard, Excess Shelter, and the Earned Income Deduction.
The mother gets a whole $16/month from SNAP
That 9.3% comes to $1.48 -- about the cost of a 2 liter bottle per month.
