Let's use the variable, x, to represent the unknown number.
We can represent the words, "the sum of a number and six, as : x + 6
The words, " 2 less than the sum", can be represented as: x + 6 - 2
The words, "the product of the number and three", can be written as: 3x
Now create an equation using "is equal to" to join the expressions:
x + 6 -2 = 3x
Now combine like terms and use inverse operations to solve for x:
x + 6 -2 = 3x
x + 4 = 3x
x + 4 - x = 3x - x
4 = 2x
4/2 = 2x/2
2 = x
The unknown number is 2

Answer:
31.35%
Step-by-step explanation:
<h3><u>Initial</u><u> </u><u>reading</u><u>:</u></h3>
In the box, there are:
- 6 Black pens
- 4 blue pens
- 7 red pens
Total number of pens in the box = 6 + 4 + 7
<u>= 17</u>
<em>If we count pens as outcomes the total number of possible outcomes are 17</em>.

<h3><u>New</u><u> </u><u>reading</u><u>:</u></h3>
Clarissa takes out a black pen from the box.
That reduces the number of black pens by 1 which increases the total number of pens by 1 as well.
So now:
- Number of black pens = 6 - 1 =<u> 5 </u>
- Total number of pens = 17 - 1 =<u> </u><u>16</u><u> </u>
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
<h3><u>Probability</u><u>:</u></h3>

If we want her to pick up a black pen, and she ends up picking one. So, we can say that the outcome is in our favor.
That makes it,
- the number of favorable outcomes = number of black pens
= 5
- and total outcomes = Total number of pens
= 16

For showing it as some percent we'll just multiply the fraction by 100

$54.29
This is because 5% of $51.70 is $2.59. The sum of the tax and bill would become $54.29.
