Best ResponseYou've already chosen the best response.0yep, but it wants the answer as a monthly amount so $250 total lost in 7 months = 250/7 per month = about $35.71/month

Best ResponseYou've already chosen the best response.0ok, so the answer isn't linear then 35.71 is based on a fixed rate of change per month so lets try a % based answer

Best ResponseYou've already chosen the best response.0so A = P (1+rt) Amount (A) = Principal (P) ( 1 + Rate(r) x Time (t) ) have u used this formula before?

Best ResponseYou've already chosen the best response.0800 = 1050 (1 + 7r) 800/1050 = (1 + 7r) r = 0.034 per month as a percentage = 3.4% per month
