Jake forgot to replace the cap on a bottle of cologne. The cologne began to evaporate at a rate of 18% per day. If the original amount of the cologne in the bottle was 50 grams, I need to draw this graph that best represents the amount of cologne f(x) remaining in the bottle after x days

Hm. Do you know what the equation would look like for this type of problem?

anonymous · Answer

No

anonymous · Answer

It's going to be$$y=50(0.18)^x$$where 50 is your starting amount, 0.18 is the percent it decreases and x is the days after Jake left the cap off. Do you know how an exponential graph looks?

50 is initial

gorv · Answer

first day
50*18/100=9 gram
remaining=50-9=41
2nd day 
41*18/100=7.38

so after x days 
remain
= 50-50*(18)^x

So it will start at 50 and the next point is 41 drops to 7.38 so|dw:1411835261626:dw|
