Maria's deduction for tax is 2000 x 20% = $<<2000*20*.01=400>>400.
Her deduction for insurance is 2000 x 5% = $<<2000*5*.01=100>>100.
Maria's total deductions is $400 + $100 = $<<400+100=500>>500.
After the deductions, Maria has only $2000 - $500 = $<<2000-500=1500>>1500 left from her salary.
Then, Maria pays $1500/4 = $<<1500/4=375>>375 for the utility bills.
So, Maria has $1500 - $375 = $<<1500-375=1125>>1125 after the deductions and utility bills payment.
