Calculate Dolly's taxable income: 51678 − 8350 − ( 2 × 3650 ) = 36028
Calculate Emiliano's taxable income: 45231 − 5700 − ( 1 × 3650 ) = 35881
Calculate Jerry's taxable income: 48099 − 5700 − ( 2 × 3650 ) = 35099
Calculate Yolanda's taxable income: 55587 − 8350 − ( 3 × 3650 ) = 36287
Jerry has the lowest taxable income: C. Jerry
Explanation
Understanding the Problem We are given the gross income, standard deduction, and number of exemptions for four workers. We need to calculate the taxable income for each worker and determine who had the lowest taxable income. The formula for taxable income is:
Taxable Income = Gross Income - Standard Deduction - (Number of Exemptions × Exemption Amount)
Calculating Dolly's Taxable Income First, let's calculate Dolly's taxable income: Gross Income = $51,678 Standard Deduction = $8,350 Number of Exemptions = 2 Exemption Amount = $3,650
Taxable Income = $51,678 - $8,350 - (2 × $3,650) Taxable Income = $51,678 - $8,350 - $7,300 Taxable Income = $36,028
Calculating Emiliano's Taxable Income Next, let's calculate Emiliano's taxable income: Gross Income = $45,231 Standard Deduction = $5,700 Number of Exemptions = 1 Exemption Amount = $3,650
Taxable Income = $45,231 - $5,700 - (1 × $3,650) Taxable Income = $45,231 - $5,700 - $3,650 Taxable Income = $35,881
Calculating Jerry's Taxable Income Now, let's calculate Jerry's taxable income: Gross Income = $48,099 Standard Deduction = $5,700 Number of Exemptions = 2 Exemption Amount = $3,650
Taxable Income = $48,099 - $5,700 - (2 × $3,650) Taxable Income = $48,099 - $5,700 - $7,300 Taxable Income = $35,099
Calculating Yolanda's Taxable Income Finally, let's calculate Yolanda's taxable income: Gross Income = $55,587 Standard Deduction = $8,350 Number of Exemptions = 3 Exemption Amount = $3,650
Taxable Income = $55,587 - $8,350 - (3 × $3,650) Taxable Income = $55,587 - $8,350 - $10,950 Taxable Income = $36,287
Determining the Lowest Taxable Income Comparing the taxable incomes: Dolly: $36,028 Emiliano: $35,881 Jerry: $35,099 Yolanda: $36,287
The lowest taxable income is $35,099, which belongs to Jerry.
Examples
Understanding taxable income is crucial for personal finance. Calculating taxable income helps individuals determine their tax obligations and plan their finances effectively. By subtracting deductions and exemptions from gross income, individuals can accurately assess their tax liability and make informed decisions about savings, investments, and tax planning strategies. This knowledge empowers individuals to manage their finances responsibly and optimize their tax outcomes.
