Iturn on the sprinkler for my children to run around outside under. at first the water is flowing at a rate of 10ft/sec. then i turn up the flow so that each second the rate increases by 19%

using pemdas, (order of operations) you'll see the answer is 24.

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 !
