2 people can paint a fence in one hour. How long would it take 10 people?
Give your answer in minutes.

12 minutes

Step-by-step explanation:

1 hour = 60 minutes

2 people can paint a fence in 60 minutes

If 5 times as many people paint a fence, it will only take 1/5 of the time as it takes 2 people to paint the fence

60 * 1/5 = 12

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
