Final answer:
The net cash change from investing activities is $5,500.
Step-by-step explanation:
The net cash change from investing activities can be calculated by subtracting the net increase in cash from operating activities and the net decrease in cash from financing activities from the net change in cash. In this case, the net change in cash is $13,000 - $4,000 = $9,000. Therefore, the net cash change from investing activities is $9,000 - $9,000 - (-$2,500) = $5,500.
