Compute the sales tax on the following transactions. An article retails for $38.50. The city sales tax is 4%, and the federal excise tax is 7%. How much is the total tax? A. 1.54 B. 2.70
C. 4.24
D. 34.26

Answers

Answer 1
Answer:

The answer is C) 4.24

4% + 7% = 11%

to get 11% of 38.50 you move the decimal two spaces to the left on the percent and multiply that number by the other number.

11% ---> .11

38.50 x .11= 4.24.

I hope this answer gave you a better understanding on how to work with percentages! :) Have a good day :)

Which monomials are perfect squares? Check all that apply. 6x2 9x8 16x9 25x12 36x16

Answers

Answer: 9x^8, 25x^(12) , 36x^(16)

Step-by-step explanation:

Let's check all the monomials

6x^2

Here 6 is not square digit, hence this monomial is not a perfect square.

9x^8=(3)^2(x^4)^2 =(3x^4)^2

Here 9 is a square digit and the power of x i.e. 8 is multiple of 2 .

Hence, this monomial is a perfect square.

16x^9

Here 16 is a square digit but the power of x i.e.9 is not multiple of 2 .

Hence, this monomial is not a perfect square.

25x^(12) =(5x^6)^2

Here 25 is a square digit and the power of x  i.e. 12 is multiple of 2 .

Hence, this monomial is a perfect square.

36x^(16)=(6x^8)^2

Here 36 is a square digit and the power of x i.e.16 is multiple of 2 .

Hence, this monomial is a perfect square.

The cost of 8 muffins and 2 quarts of mil is $18. The cost of 3 muffins and 1 quart of milk is $7.50 hos much does 1 muffin and 1 quart of milk cost ?

Answers

Answer:

The cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .

Step-by-step explanation:

Let us assume that the cost of one muffins be x.

Let us assume that the cost of one 1 quarts of milk be y.

As given

The cost of 8 muffins and 2 quarts of mil is $18.

Than the equation becomes

8x + 2y = 18

As given

The cost of 3 muffins and 1 quart of milk is $7.50.

Than the equation becomes

3x + 1y = 7.50

Two equations are

8x + 2y = 18  and 3x + 1y = 7.50

Multiply  3x + 1y = 7.50 by 2 and subtracted from 8x + 2y = 18 .

Thus

8x - 6x + 2y - 2y = 18 - 15

2x  =  3

x = (3)/(2)

x = 1.5

Put x = 1.5 in 3x + 1y = 7.50

3 × 1.5 + y = 7.50

y = 7.50 - 4.5

y = 3

Therefore the cost of the 1 muffin is $1.5 and 1 quart of milk cost is $3 .
