Answer:
250
Explanation:
To determine the original number of jellybeans in the jar, we can set up the following equation:
Let's assume the original number of jellybeans in the jar is "x".
60% of jellybeans were eaten, so there are 100 jellybeans left, which represents 40% of the original amount.
40% of x = 100
To find x, we can set up the equation:
0.4x = 100
To solve for x, we divide both sides of the equation by 0.4:
x = 100 / 0.4
x = 250
Therefore, there were originally 250 jellybeans in the jar.
