Answer:

D)  9:20 am

Step-by-step explanation:

Train A's route = 20 mins

Train B's route = 80 mins

80 ÷ 20 = 4

Therefore, Train B's route is 4 times the length of Train A's route.

Therefore, the time Train A and B will leave the station at the same time will be the first time Train B leaves after 8am.

1 hour = 60 minutes

8am + 80 minutes = 8am + 1 hr + 20 minutes = 9:20 am

Carol is single and has an adjusted gross income of $32,785. She claims one exemption of $8200. What is her tax due?
LenKa [72]

Answer

A = 3321

Step-by-step explanation:

The reason for this answer is to get the Taxable income, you go by this equation AGI - (Exemptions + Deductions) since there is no deductions here we leave that part out. Subtract the AGI (32785) - 8200 the Exemption and you get 24585 then if we look on the chart, she is single and she falls under the answer of 3321!

Hope this helps, sorry I am a little late. I just got this answer too. :)
