Answer:
5 gallons
Step-by-step explanation:
We can use ratios to solve
5/12 gallon x gallons
---------------- = -------------------
1/24 minute 1/2 minute
Using cross products
5/12 * 1/2 = x *1/24
5/24 = x/24
Multiply each side by 24
24*5/24 = x/24*24
5=x
We can pump 5 gallons

The question is to find an expression for the expenses
<u>Answer:</u>
E (x) =n + 5
<u>Explanation:</u>
The profit is defined as the difference between the revenue and the expenses.
<u>This means that:</u>
profit = revenue - expenses
<u>Now, we rearrange the equation to solve for expenses:</u>
expenses = revenue - profit
<u>From the given, we know that:</u>
expression for revenue is 18n
expression for profit is 17n - 5
<u>Substitute in the equation to get expression for expenses as follows:</u>
E (x) = 18n - (17n - 5)
E (x) = 18n - 17n + 5
E (x) = n + 5
Hope this helps :)
