You work at a delivery company. Your boss wants you to determine the average cost of diesel per mile for 9 old delivery trucks. On an average day, the old trucks use a total of 180 gallons of diesel and travel 1,980 miles. Additionally, he wants you to determine
the average cost of diesel per mile for 3 new delivery trucks. On an average day, the new trucks use a total of 44 gallons of diesel
and travel 660 miles. If diesel is $3.30 a gallon, what is the difference between the old and new trucks in average cost for diesel
per mile.
Your Calculation:
1,980 = 180 = 11 miles/gallon
3.30 - 11 = $0.30 per mile
And
660 = 44 = 15 miles/gallon
3.30 – 15 = $0.22 per mile
Therefore, 0.30-0.22 -0.08per mile
Is there a mistake in the calculation? If so, Identify the mistake.

Me! 50 points! why does when we come home, our door is unlocked and there is grease on the door knob, me solve this , and i don't know what category this goes under

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i. e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
