Calculation for Job A:
Annual salary = $42100
Standard deduction = $5700
Exemption = $3650
Taxable amount = 42100 - 5700 - 3650 = $32750
32750 belongs to catagory 8350-33950 of the given table.
So the tax will be = 835 + 15% of (32750-8350)
= 835 + 0.15(32750-8350)
= 835 + 0.15(24400)
= 835 + 3660
= 4495
Pay after tax = 42100- 4495 = $37605
Calculation for Job B:
Annual salary = $44400
Standard deduction = $5700
Exemption = $3650
Taxable amount = 44400 - 5700 - 3650 = $35050
32750 belongs to catagory 33950-82250 of the given table.
So the tax will be = 4675 + 25% of (35050-33950)
= 4675 + 0.25(35050-33950)
= 4675 + 0.25(1100)
= 4675 + 275
= 4950
Pay after tax = 44400- 4950 = $39450
Now we can easily find difference between payment of both jobs after tax = 39450-37605= $1845
Hence final answer is $1845.
