Answer:
A) Charlotte's taxable income = salary - short term capital loss + cash price - standard deduction (larger than itemized deduction) = $80,000 - $2,000 + $4,000 - $24,000 = $58,000
B) Charlotte's tax liability during 2018 = $1,905 + [($58,000 - $19,050) x 12%] = $1,905 + ($38,950 x 12%) = $1,905 + $4,674 = $6,579
C) Charlotte's child and dependent tax credit for 2018 = ($2,000 x 4 children) + ($500 x 2 parents) = $8,000 + $1,000 = $9,000
