Math Problem Statement
A publication that reported on the most effective ways to solve a city's homelessness problem claimed that if its suggestions are followed and implemented, a city with A individuals experiencing homelessness this year can expect to have H homeless people t years later, according to the model
H left parenthesis t right parenthesis equals A e to the power of negative 0.16 t end exponent
Given this model, in how many years can the city expect a reduction of 90% of its population experiencing homelessness?
Enter your answer as a number (no labels) and round to the nearest tenth of a year.
