Demi loves gummy bear so much that after returning from QFC with some gummy bears to eat 5% of the Gummi Bears he just bought the next day heat 5% of the remaining gummy bears and continues to eat another 5% each day what percent of the gummy bears will Danny have left after 6 days round your answer to the nearest whole percent ​

we have that

Let

x -----> original amount

so

1) eat 5% of the Gummi Bears he just bought

remaining-------> 95%

2) the next day heat 5% of the remaining gummy bears

5%=0.05

95%*(0.05)=4.75%

Remaining=95%-4.75%=90.25%

3) third day

90.25%*(0.05)=4.5125%

Remaining=90.25%-4.5125%=85.8375%

4) 4 day

85.8375%*(0.05)=4.286875%

Remaining=85.8375%-4.286875%=81.550625%

5) 5 day

81.550625%*(0.05)=4.07753125%

Remaining=81.550625%-4.07753125%=77.47309375%

6) 6 day
