can someone just tell me if I'm right?

and if I'm wrong please tell me what i'm missing.

1. Daniel Simmons arrived at the following tax information:

Gross salary, $62,250

Dividend income, $140

Standard deduction, $12,400 Interest earnings, $75

Adjustments to income, $850

What amount would Daniel report as taxable income? (LO3.2)

AGI= gross income-adjustments to income Taxable income= AGI-standard deduction OR total itemized deductions.

62,000-850=61,150

AGI=61,150

AGI-Standard deduction=61,150-12,400=48,750

Taxable income= 48,750

2. If Samantha Jones had the following itemized deductions, should she use Schedule A or the standard deduction? The standard deduction for her tax situation is $12,400. (LO3.2) Donations to church and other charities, $5,050

Medical and dental expenses exceeding 10 percent of adjusted gross income, $2,450

Mortgage interest, $3,100

State income tax, $2,920

5,050+2,450+3,100+2,920=13,520

Using Schedule A would grant Samantha a greater deduction.

Samantha should use Schedule A.

4. Based on the following data, would Beth and Roger Simmons receive a refund or owe additional taxes? (LO3.2)

Adjusted gross income, $42,140

Credit for child and dependent care

expenses, $400 Standard deduction, $24,800

Federal income tax withheld, $2,017

Tax rate on taxable income, 10 percent

AGI-standard deduction= 42,140-24,800=14,340

14,340x10%=1,434

1,434-400=1,034

Tax owed= 1,034

They will receive a refund.

Tax withheld-tax owed=refund

2,017-1,034=983

Refund=983
