In 1992, only 275 people owned cellphones in Metropolis. Each year, cell phone use has continuously grown by 82%. How many cellphone users were there in 2000?
For this case we have the following equation of the potential type: y = A (b) ^ t Where, y: number of people with cell phones A: initial number of people with cell phones b: growth rate t: time Substituting values: y = 275 * (1.82) ^ t For the year 2000 we have t = 8. Substituting: y = 275 * (1.82) ^ 8 y = 33105.77794 nearest whole integer: y = 33105 Answer: there were 33105 cellphone users in 2000
