Answer:
$25.5
Step-by-step explanation:
Sure, so the total of the
Item:
30 Dollars ($)
and the discount price is
15 percent (%)
So 30 times 0.15 because 30 is the price in total and 0.15 is the percentage but in a decimal form.
30 times 0.15 equals 4.5
4.5 is the amount that 15 % equals.
30 minus (-) 4.5 because once again the total is 30 and since we have a discount price then we minus (-) the discount price by the total and you get
A total with the discount price as 25.5 Dollars or $25.5
Hope this helps ;)

Answer:
<em>It will take 12 hours to fill the tank</em>
Step-by-step explanation:
Proportions
Tap A fills a tank in 4 hours. It means each hour it fills 1/4 of the tank.
Tap B fills the tank in 3 hours. Each hour it fills 1/3 of the tank.
Tap C empties the tank when full in 2 hours. Each hour it empties 1/2 of the tank.
Each hour, the tank gets filled by:
![\displaystyle \frac{1}{4}+\frac{1}{3}-\frac{1}{2}=\displaystyle \frac{3}{12}+\frac{4}{12}-\frac{6}{12}=\frac{3+4-6}{12}=\frac{1}{12}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B1%7D%7B4%7D%2B%5Cfrac%7B1%7D%7B3%7D-%5Cfrac%7B1%7D%7B2%7D%3D%5Cdisplaystyle%20%5Cfrac%7B3%7D%7B12%7D%2B%5Cfrac%7B4%7D%7B12%7D-%5Cfrac%7B6%7D%7B12%7D%3D%5Cfrac%7B3%2B4-6%7D%7B12%7D%3D%5Cfrac%7B1%7D%7B12%7D)
Since the tank fills 1/12 of its capacity in one hour, it follows that it will take 12 hours to fill the tank
