Answer:
D. 1.06(3.19x + 1.20y + 1.20z)
Step-by-step explanation:
Since marker packs are 3.19 each, the cost of the marker packs she buys can be represented by 3.19x.
All spiral notebooks are 1.20 each, so the cost of the wide ruled notebooks can be represented by 1.20y.
The cost of the college ruled notebooks can be represented by 1.20z.
In the expression, all of these terms have to be added together and multiplied by 1.06 to calculate the sales tax.
So, the expression will be 1.06(3.19x + 1.20y + 1.20z)
D is the correct answer
Usually, you CAN'T turn a fraction into a whole number.
You can ONLY do it when the top number is a multiple
of the bottom number. Otherwise, it's not possible.
IF the top number is a multiple of the bottom number,
then take the bottom number, and divide both the top
and the bottom of the fraction by it. Then the top number
will be the whole number that's equal to the original fraction.
Examples:
12 / 5 . 12 is not a multiple of 5 , so there is
NO whole number that's equal to 12/5 .
5 / 12 . Same thing. 5 is not a multiple of 12 .
12 / 3 . 12 is a multiple of 3 .
Divide top and bottom by 3 .
Then you have 4 / 1 .
4 is the same as 12/3 .
Answer:
-1
Step-by-step explanation:
Find the difference of each sequence
19 - 15 = 4
15 - 11 = 4
11 - 7 = 4
7- 3 = 4
3 - ? = 4
Subtract 4 from the 3
3 - 4 = -1
Therefore, the next term is -1
