The cost of gas for a truck is $3.59. The gas tank holds 28.2 gallons when empty, but it is 1/5 full now. How much will it cost to fill the tank?
Explain in writing how you completed the task. What did you do and in what order did you do it?
After you have written the explanation of your work process, think about this question. Can you see another, different way to complete the problem; a different process? If you can, write out that explanation, step by step. Once you have done that, try the second way and see if you get the same answer.
Finally, if you did any rounding of decimals in your work process, think about how that might have impacted your accuracy. It is usually best to not do any rounding until the end.
An answer and explanation will be published in another post soon.
