Johanna purchases a book for $14.95. There is a sales tax of 6.5%. How much is the final price with tax? What is the total? What is the percent? Use the formula amount = total x percent to find the amount of the sales tax. To find the final price, add the cost of the book to the amount of tax.

Answers

Answer:

Tax = $0.97175

Final Price = $15.92175

Step-by-step explanation:

To calculate the amount of tax of an amount you just must multiply this figure by the percentage of the tax expressed in decimal numbers.

-----------------------------------------------------------------------------------------------

Data:

Price = $14.95

Tax rate = 6.5%

-----------------------------------------------------------------------------------------------

Calculation of tax:

amount = total x percent = $14.95 x 6.5% = $14.95 x 0.065 = $0.97175

Calculation of the final price with tax:

Amount = book cost + tax = $14.95 + $0.97175 = $15.92175

-----------------------------------------------------------------------------------------------

Tax = $0.97175

Final Price = $15.92175

-----------------------------------------------------------------------------------------------

Hope this helps!

Okay so 6.5% of $14.95 is 0.97175. That rounds to 0.97. And to get the total we just add 0.97 to 14.95. Our answer is 15.92. However if you don't want to round then you would add 14.95 and 0.97175 . This would give you15.92175. Hope this helps!

A bag had 3 pink marbles and 4 purple marbles find the probability of selecting 3 pink marbles without replacement

Answers

There are 7 marbles in the bag.
The probability of drawing a pink one is (3/7) .

Then you have 1 pink one, and there are 6 marbles in the bag.
The probability of drawing a pink one is (2/6) .

Then you have 2 pink ones, and there are 5 marbles in the bag.
The probability of drawing a pink one is (1/5) .

The probability of all 3 draws being successful is

(3/7) (2/6) (1/5) = 6/210 = 1/35 = about 2.86% (rounded)

4:3 and 25:45 are equal ratios true or false

Answers

False.

The scale factor for 3 and 45 is 15.

45 / 3 = 15.

We know that 25 isn't even a whole number for the scale factor, because no number x 4 can equal 25 (whole numbers only).

25 / 3 = 6.33333
