Answer:
$1800
Step-by-step explanation:
The tax due is ...
3% × $10,000 + 5% × ($40,000 -10,000)
= 5% × $40,000 - (5% -3%)($10,000)
= $2000 - 200
= $1800 . . . . tax due

<em>Additional comment</em>
The table is structured so you need to compute the amount due in each bracket and add those to find the total due.
I prefer to compute the tax due by applying the appropriate tax rate to the whole amount, then subtracting a "discount" that reflects the fact that the rate doesn't actually apply to the whole amount.
