Need a good explanation please :)

She is considering applying for a second part-time job that would give her an additional $10,000 of taxable income. By how much will the income from the second job increase her tax liability? (Use the tax rate schedules.) Multiple Choice $1,000 $1,200 $1,300 $2,400
