A forestry service person plants seedlings in a field. Each week, she monitors the field, recording the number of dead or dying seedlings and planting new seedlings. A negative value indicates an overall loss of seedlings, and a positive value indicates an increase in the number of seedlings observed each week. Her data for the 4 weeks in June include –14, 22, 16, –4. If the data are expected to remain consistent through 3 months of summer, how many overall seedlings will be in the field at the end of the 3 months? 20
