Antonia is printing greeting cards. she paid a setup fee of 25 dollars and will pay 55 cents for each printed card. how many cards must antonia print in order to make the average cost per card 75 cents?

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

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 !
