Let's assume the total number of jellybeans in the bag is "x".
We are given that 15% of the jellybeans in the bag are black, so the number of black jellybeans is 0.15 * x.
We are also given that 136 jellybeans are red and the remaining "r" jellybeans are black. So, the number of black jellybeans is x - 136.
Now we can set up an equation:
0.15 * x = x - 136
0.15x = x - 136
0.15x - x = -136
-0.85x = -136
Divide both sides of the equation by -0.85 to solve for x:
x = -136 / -0.85
x = 160
Therefore, the total number of jellybeans in the bag is 160.
The correct answer would be A) 151, which is not among the given options.
To find the total number of jellybeans in the bag, we need to determine the number of black jellybeans based on the given information.
Let's assume that the total number of jellybeans in the bag is represented by "x".
From the question, it is stated that 136 jellybeans are red, and the remaining jellybeans (r) are black.
We know that the percentage of black jellybeans is 15%. So we can write this as an equation:
(r / x) * 100 = 15
Simplifying the equation, we have:
r = (15/100) * x
r = (3/20) * x
Now, we can substitute the value of "r" into the first equation:
136 + r = x
136 + (3/20) * x = x
To solve this equation, we need to get rid of the fraction. We can do this by multiplying everything by 20:
2720 + 3x = 20x
Next, we subtract 3x from both sides:
2720 = 17x
Finally, we divide both sides by 17 to isolate x:
x = 2720 / 17
x = 160
Therefore, the total number of jellybeans in the bag is 160.
Since none of the given options match this result, it is possible that there is an error in the question or given options.
