answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

it is a secret for it not to be compromised sorry

step-by-step explanation:

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 !
