Each day grace eats 40 % of the gummy bears left in a bag at that time .at the end of the second day 27 gummy bears remain how many gummy bears were in the bag at the first day

75

Explanation:

Grace has been eating gummy bears for two days.

 Let n = number of gummy bears at beginning of first day. Then

0.40n = number of gummy bears eaten on first day, and

0.60n = number of gummy bears remaining at end of first day

0.60n = number of gummy bears at beginning of second day.

0.40 × 0.60n = 0.24n = number of gummy bears eaten on second day

0.60n - 0.24n = 0.36n = number of gummy bears remaining at end of second day

0.36n = 27

      n = 27/0.36 = 75

There were 75 gummy bears in the bag at the beginning of the first day.
