Answer:
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.
