Answer:
There will be about 18 grams remaining.
Step-by-step explanation:
If you have 500 grams to start and it decreases by 20% each day for 15 days, you can use the following equation:
Remaining amount = [tex]500(1 - 0.20)^{15}[/tex]
Plug this into a calculator and you should get 17.59218604, which, when rounded to the nearest gram, equals 18 grams remaining.
Hope this helps!
