The pair of shoes costs $52.99, so p = 52.99.
The state sales tax is 8%, which can be changed to decimal form by dividing by 100: 8/100 = 0.08. So r = 0.08.
Now you can plug both of these values into the formula to find the total cost of the shoes (c):
c = p + r*p
c = 52.99 + (0.08)*(52.99)
c = 52.99 + 4.2392
c = 57.2292
So the total cost of the shoes is $57.23
If the variable is the same you can combine it
The first month or one month is all it takes.
In one month both have 38 dollars
Scientific notation is used so that the order of the number is known in first glance. The value of the given number in scientific notation is given by: Option B: 
<h3>How does scientific notations work?</h3>
The number is written in the form
where we have 
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
- Better readability due to compact representation
- Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
For the given case, the number in consideration is 0.0000069
Rewriting it in fraction form, we get:

(we used two facts: first that : 
and second that: 
Thus, the value of the given number in scientific notation is given by: Option B:

Answer:
Not completely sure but hopefully these will help.
Step-by-step explanation:
I'm kind of confused what you're asking for. If you could clarify that would be great. If you're trying to make it divisible by 9, you can either do 3, 6 or 9. If you want the first two digits: 2,5,8. Please clarify so I can help
