Length in feet multiplied by width in feet multiplied by height in feet divided by 27 equals cubic yards needed.
When dealing in inches: convert inches to feet by dividing by 12.
For example: pour a 25 ft. sidewalk 5 ft. wide and four inches deep.
(25’ x 5 ‘ x 0.333’) / 27 = 1.54 cubic yards
Note* we achieved 0.333 ft. by taking four inches and dividing by twelve.
Another example: yardage for an 80 ft. driveway, 24 ft. wide and 5 inches deep.
(80’ x 24’ x 0.416’) / 27 = 29.58 cubic yards

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 :)
