Answer:
The tax liability of Family A is $7,500
Explanation:
The computation of the tax liability would be
First 10,000 = $0
Next $20,000 = $20,000 × 10% = $2,000
Next $20,000 = $20,000 × 20% = $4,000
Next $5,000 = $5,000 × 30% = $1,500
So, the total tax liability would equal to
= $2,000 + $4,000 + $1,500
= $7,500
On the basis of the given income and given tax rate we calculate the liability of Family A
