![\$400](https://tex.z-dn.net/?f=%5C%24400)
Step-by-step explanation:
GIVEN: A hotel charges a
annual fee plus an additional
for each night you stay there.
TO FIND: average cost per night if you stay at the hotel for
nights.
SOLUTION:
Annual fee charged by hotel ![=\$10000](https://tex.z-dn.net/?f=%3D%5C%2410000)
amount charged each night we stay there ![=\$200](https://tex.z-dn.net/?f=%3D%5C%24200)
Total number of nights we stay ![=50](https://tex.z-dn.net/?f=%3D50)
Total amount paid for
nights![=50\times\$200](https://tex.z-dn.net/?f=%3D50%5Ctimes%5C%24200)
![=\$10000](https://tex.z-dn.net/?f=%3D%5C%2410000)
Total amount paid ![=\text{annual fee}+\text{total amount paid for 50 nights}](https://tex.z-dn.net/?f=%3D%5Ctext%7Bannual%20fee%7D%2B%5Ctext%7Btotal%20amount%20paid%20for%2050%20nights%7D)
![=\$10000+\$10000](https://tex.z-dn.net/?f=%3D%5C%2410000%2B%5C%2410000)
![=\$20000](https://tex.z-dn.net/?f=%3D%5C%2420000)
average cost per night ![=\frac{\text{total amount paid}}{\text{total number of nights of stay}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctext%7Btotal%20amount%20paid%7D%7D%7B%5Ctext%7Btotal%20number%20of%20nights%20of%20stay%7D%7D)
putting values,
average cost per night ![=\frac{20000}{50}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B20000%7D%7B50%7D)
![=\$400](https://tex.z-dn.net/?f=%3D%5C%24400)
Hence average cost per night if we stay at hotel for
days is ![\$400](https://tex.z-dn.net/?f=%5C%24400)
Answer:
Step-by-step explanation:
The product of two rational numbers is
a rational number because multiplying two rational numbers is equivalent to the ratio of two integers, which is a rational number.
I think this is your answer but i'm not sure. Hoped it helped!
The correct answer is B
<h2><u>EXPLANATION</u></h2>
The commutative property of multiplication says that, if you are multiplying two numbers, the order of the multiplication does not matter. You will get the same result, no matter which one you bring first or second during the multiplication process.
That is, if <em>a </em>and <em>b</em> are two real numbers, then the commutative property of multiplication says that,
![a\times b = b\times a](https://tex.z-dn.net/?f=a%5Ctimes%20b%20%3D%20b%5Ctimes%20a)
So for the above options,
![6\times 4 = 4\times 6](https://tex.z-dn.net/?f=6%5Ctimes%204%20%3D%204%5Ctimes%206)
![24= 24](https://tex.z-dn.net/?f=24%3D%2024)
<em>Note that the numbers have not changed, so their values will not change also. </em>
We are NOT referring to a situation where the numbers will change whilst their values is still the same.
The percent change if a city that used to produce 2050 kilowatt hours has reduced their consumption to 1125 kilowatt hours is 45.122% decrease.
<h3>What is percentage change?</h3>
Percent increase and percent decrease are measures of percent change, which is the extent to which a variable gains or loses intensity, magnitude, extent, or value.
we know,
% change = (final- initial) / initial * 100
=(1125-2050)/1125 *100
=45.122%
Hence, percentage change be 45.122% decrease.
