Please help me quickly! 3.5.2 Practice for income tax

Answer:
$15,475
Step-by-step explanation:
Mr. and Mrs. Jones make a combined $92,400 in taxable income. Looking at the table, their income is over $67,900 but not over $137,050.
So, the tax is $9,350. But, it also includes 25% of the amount over $67,900.
So,
$92,400 - $67,900 = $24,500
0.25 × $24,500 = $6,125
$9,350 + $6,125 = $15,475
Hope that helps.
