Final answer:
When an investment loss of $22,200 is shared among 6 people, each person incurs a loss of -$3,700, represented by a negative integer.
Step-by-step explanation:
If an investment loses $22,200 and this loss is shared equally among 6 people, we calculate the loss per person by dividing the total loss by the number of people.
The calculation is $22,200 divided by 6, which equals $3,700. Since this is a loss, we use a negative integer to describe the loss for each person. Consequently, the loss for each person would be -$3,700.
