Question

1) $1,800,000 2) $288,000 3) $450,000 4) $352,800 1) $1,800,000 2) $288,000 3) $450,000 4) $352,800 1) $1,800,000 2) $288,000 3) $450,000 4) $352,800 Suppose that the total salary of all the employees at a factory in a certain city is $300,000. Of this salary, sixty% is spent in the city. Of the money spent in the city, sixty% is again spent in the city. If this continues indefinitely, how much total money is spent in the city, that is, how much of an effect does the original total salary have on the local economy?

Explanation / Answer

total money = sum of (0.6)^n*300,000
but this is geometric series

= 1/(1-0.6)*300,000 = 300,000/0.4= 750,000

so effect was 750000-300000 = 450,000

so 3)
