Question

Salicylate is active in aspirin. The following table shows the amount of salicylate in the bloodstream of a certain person t minutes after ingesting 200 milligrams of aspirin

Time (min)	0	20	40	60	80	100	120
Salicylate (mg)	200	177	157	144	123	114	99

Use exponential regression to write an exponential decay function for A, the milligrams of salicylate remaining t minutes after ingesting the aspirin. Round constants to the nearest thousandth. (Enter a mathematical expression)

1. A=
