where 
represents the population of the island in 1990.
How does the model differ from the actual values?
A. The display indicates that for the year 1993, the model gives a value of about 89 people, which is slightly more than the actual value of 88 people. B. The model does not differ from the actual figures. C. The display indicates that for the year 1993, the model gives a value of about 88 people, which is slightly less than the actual value of 87 people. D.
