Also.. ther r online calculator which can di that... http://easycalculation.com/statistics/regression.php so.. the function for the problem is.. f(x) =1.2727x + 30.54 which can be round off to f(x) = 1.27x + 30.5 now to find the amount on November find f(11) which is 1.27(11) + 30.5 =44.47 = 44.5 to find the amount in December find f(12) which is 1.27(12) + 30.5 =45.74 = 45.7 to find the month which will exceed 50 000 f(x) = 1.27x + 30.5 50 = 1.27x + 30.5 1.27x = 19.5 x = 15.35 which will be during the 15 th month hope this will help ya!!!
