A field currently contains 20 mint plants. Absent constraints, the number of plants would increase by 30%
each year, but the field can only support a maximum population of 100 plants. Use the logistic model to
predict the population in the next two years. Round answers to 1 decimal place.

light intensity(lux) - 5.0, 4.0, 3.0, 2.0, 1.0
depth of water(m) - 2.3, 3.1, 4.0, 5.4, 7.7
(a) use logarithmic regression to model data, round all values to the nearest hundredth
(b) At what depth, to the nearest tenth of a metre is the light intensity 3.6 lux
(c) What is the light intensity at the surface, round to the nearest tenth
