Final Answer:
Without the initial volume of paint, we cannot determine the exact amount left in the can. For the linear equation, the total time to complete a painting job can be expressed as T = 4 + 0.001S, where T is the total time in hours, and S is the size in square feet.
Step-by-step explanation:
Without the initial volume of paint, we cannot determine the exact amount left in the can. If Bill used half the amount of paint and the can was initially full, he would have half the total volume of paint remaining. However, the initial volume of paint in the can is not provided in the information given. Therefore, we cannot determine the exact amount left in the can and cannot select any of the given options (A, B, C, D) as the correct amount of cubic centimeters of paint left.
Additionally, the question involves expressing information in a linear equation related to the time it takes to complete a painting job. The setup time of four hours is fixed, while the time to complete the job per square foot is variable. The linear equation representing this scenario is:
\[ T = 4 + 0.001S \]
Where \( T \) represents the total time in hours to complete the job and \( S \) represents the size of the painting job in square feet.
