Suppose the tax rate is 0 on the first $20,000, 20 percent on the next $20,000, 30 percent on the next $20,000, 40 percent on the next $20,000, and 50 percent on all income over that. The Valenzuela family has an income of $80,000. What is the tax bill for this family?

income tax expense 18,000

Explanation:

we have to calcualte the taxable income on each bracket:

1st 20,000 tax free

$20001 to $40,000 are taxes at 20% Thus, 4,000 income tax

$40,001 to $60,000 are taxes at 30% Thus, 6,000 income tax

$60,001 to $80,000 are taxes at 40% Thus, 8,000 income tax

In total the income tax will be for $18,000
