I do not think it is okay to label time axis to the nearest ten thousandths of a second. A second is the SI unit of time and 60 seconds make up a minute. Conversion of a second to ten- thousandths would result to a figure that is cannot be easily measured. The second will be too small.
First, I added $2.82 and $1.43. Then, I subtracted the sum ($4.25) from $20. Lastly, I divided the difference($15.75) by five because there were five pineapples. Which gave me the answer: $3.15.
