Answer:

A : 1/4

B : 19/100

C : 3/50

Step-by-step explanation:

There are 25 prime numbers from 1 to 100.

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97.

25/100 = 1/4

There are 19 numbers that contain 9.

9, 19, 29, 39, 49, 59, 69, 79, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99.

19/100

There are 6 numbers that are prime and contain 9.

19, 29, 59, 79, 89, 97.

6/100 = 3/50

Answer:

Your answer choice is correct: the range 15,000–40,000

Step-by-step explanation:

Above income of 15,000 and below income of 40,000, the problem statement tells us the tax rate is 5%. If income amount is represented by x, then .05x is the amount of the tax (subject to the credits offered by the graduated scale). The term 0.05x in the question tells you the applicable range is 15,000 ≤ x ≤ 40,000.

If 15,000 were taxed at the 5% rate, the tax amount would be $750. Instead, the tax amount on that income is 3% of 15,000, or $450—a tax that is $300 less than 0.05x. Hence in the range 15,000–40,000, the tax computation is ...

... f(x) = 0.05x -300 . . . . . for 15,000 ≤ x ≤ 40,000

_____

<em>Above 40,000</em>

At the middle income tax rate, $40,000 would have a tax of ...

... 0.05×40000 -300 = 1700

At 7%, $40,000 would have a tax of

... 0.07×40000 = 2800

Then the actual tax on amounts above $40,000 is $1100 less than 7% of the income.

... f(x) = 0.07x -1100 . . . . . for x ≥ 40,000

1. Is the actual equation, so this is Given

2. removing the parenthesis is the Distributive Property

3. Combining like terms.

4. They add 6x to both sides, this would be the Addition Property of Equality

5. Subtract 4 from both sides, this is the Subtraction Property of Equality.

6. Divide both sides by 8, this would be the Division Property of Equality.
