One hundred fifty-seven millionths. Hope that helps!
Answer:
The correct option is c.
Step-by-step explanation:
It is given that Judy completes a puzzle by herself, it takes her 3 hours.
The part of puzzle completed by Judy in one hour is
.
Rate is a part of word done by a person in one unit of time.
It means the Judy's rate to complete the puzzle is
.
Therefore the correct option is c.
Given:
Consider the given equation is:

To find:
The missing exponent.
Solution:
Let x be the missing exponent. Then the given equation can be written as

It can be rewritten as:

![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)
On comparing the coefficient of m, we get



Therefore, the value of the missing exponent is 8. So, the complete equation is
.
8.25% of 55.60 = 4.58700
We round that number to 4.59
(I am assuming the tip is based on the amount of the pretax bill.)
15% of 55.60 = 8.34
So $55.60 + $4.59 + 8.34 = $68.53
The bill would be $68.53.
Let
x------> the first even integer
x+2---->the second even integer
x+3---->the third even integer
we know that
-----> equation that represent the situation
solve for x
Combine like terms in the left side


therefore
<u>the answer is the option B</u>
