HELP ASAP 10 POINTS TO BRAINLIEST
Brilliant_brown [7]

Answer:

15%

Step-by-step explanation:

The cost of 2 adults and 2 children without the discount is

2 adults = 2 (55) = 110

2 children = 2 (45) = 90

Total cost = 110+90 = 200

The original price is 200 and the new price is 170

Percentage discount = (Original price - new price)/ original price * 100%

                                     = (200-170)/200 * 100%

                                     = 30/200 * 100%

                                     = .15 * 100%

                                     = 15%

Laura is a single taxpayer, she has $35,000 in ordinary taxable income and $5,000 in capital gains on an investment she held for
Kay [80]

Going by the information given above, Laura is most likely going to belong to the tax bracket where the rate payable is 12%. This is because she is a single filer and her income is between $10,276 and $41,775.

<h3>What is a tax bracket?</h3>

Tax brackets are a series of income and tax layers by which people are defined based on how much they earn per annum.

The tax rates range from 10% to 37%. The rate applicable to a person or group of persons depends on

  • whether or not they are single
  • If married, whether they are filing jointly; and
  • how much their annual income is subject to deductibles.

It is to be noted that a general answer was provided here due to insufficient details in the question.
