Question

The population of a town has been growing, following the equation P=800t+6000P=800t+6000, where t is years after 2010. The number of restaurants in the town has been growing according to the equation R=3t+35R=3t+35.

Complete an equation for the number of restaurants per capita (per person)

Restaurants per capita:   

How many restaurants per capita does this model predict for the year 2015?   

Answer 1

P=800t+6000

R=3t+35

R/P = (3t + 35) / (800t + 6000)

In 2015, t = 2015 - 2010 = 5 hence R/P = 50 / 10,000 = 1 / 200
