Answer:
![160\ \text{s}](https://tex.z-dn.net/?f=160%5C%20%5Ctext%7Bs%7D)
Step-by-step explanation:
The inequality that represents the situation is
where
is the time in seconds
![\Rightarrow -2.5t](https://tex.z-dn.net/?f=%5CRightarrow%20-2.5t%3C100-500)
![\Rightarrow -2.5t](https://tex.z-dn.net/?f=%5CRightarrow%20-2.5t%3C-400)
![\Rightarrow 2.5t>400](https://tex.z-dn.net/?f=%5CRightarrow%202.5t%3E400)
![\Rightarrow t>\dfrac{400}{2.5}](https://tex.z-dn.net/?f=%5CRightarrow%20t%3E%5Cdfrac%7B400%7D%7B2.5%7D)
![\Rightarrow t>160\ \text{s}](https://tex.z-dn.net/?f=%5CRightarrow%20t%3E160%5C%20%5Ctext%7Bs%7D)
So, the time after which there will be less than 100 gallons of water is

<h2>
Step-by-step explanation:</h2>
<h3>1. Write the composite expression.</h3>
![\frac{f(4)}{g(4)}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%284%29%7D%7Bg%284%29%7D)
<h3>2. Find the result of each function through the ordered pairs.</h3>
<em>In this part, we're trying to find out what value each function gives for x= 4. As you may see in the ordered pair (4, 6), f(x) gives a value of 6 for x= 4. Also, g(x) gives a value of 7 for x= 4, according to the ordered pair (4, 7). </em>
<em>Substitute the values:</em>

![\$10.45](https://tex.z-dn.net/?f=%5C%2410.45)
</h3>
Step-by-step explanation:
CPI stands for Consumer Price Index, which is the measure of average prices to goods and services.
So, in this case, we have to find the average price for the given basket in year 2.
We know that in year 2, a toothbrush tube costs $1.25 and a tube of toothpaste costs $2.10. If we have 5 toothbrushes and 2 tubes of toothpaste, the total cost would be
![5 \ toothbrushes=5(\$1.25)=\$6.25\\2 \ toothpaste \ tubes=2(\$2.10)=\$4.20](https://tex.z-dn.net/?f=5%20%5C%20toothbrushes%3D5%28%5C%241.25%29%3D%5C%246.25%5C%5C2%20%5C%20toothpaste%20%5C%20tubes%3D2%28%5C%242.10%29%3D%5C%244.20)
Now, the CPI would be the sum of these costs
![CPI = \$6.25 + \$4.20=\$10.45](https://tex.z-dn.net/?f=CPI%20%3D%20%5C%246.25%20%2B%20%5C%244.20%3D%5C%2410.45)
Therefore, the Consume Price Index for this basket of goods is
B. ![\$10.45](https://tex.z-dn.net/?f=%5C%2410.45)
