A. The absolute minimum is at (31,622.78, 31.11). This tells us that the average cost of a graphing calculator is minimized at $31.11 per calculator when approximately 31,623 are produced.
B. The absolute minimum is at (34,825.23, 29.32). This tells us that the average cost of a graphing calculator is minimized at $29.32 per calculator when approximately 34,825.23 are produced.
C. The absolute minimum is at (31,622.78, 29.32). This tells us that the average cost of a graphing calculator is minimized at
per calculator when approximately 31,623 are produced.
D. There is no absolute maximum.
