Answer:
19 bears, 38 boxes of candy.
Step-by-step explanation:
We can use a system of equations (b = # of bears, c = # of candy boxes):
<em>b + c = 57, 8b + 6c = 380</em>.
We can use substitution by isolating b in the first eq.: <em>b = 57 - c</em>, then substitution b with 57 - c in the second eq.: <em>8(57 - c) + 6c = 380</em>.
Then, we solve: 456 - 8c + 6c = 380, 76 = 2c, c = 38 candy boxes.
Finally we plug in 38 for c in the first eq.: b + 38 = 57, b = 19 bears.
You could simulate this by allowing the numbers 1-4 to represent a correct answer and the numbers 5-6 to represent an incorrect answer. This would have a 2/3 probability of the question in the simulation being correct.
Answer:
78 + B = 91...
91 - 78 = B
91 - 78 = 13
B = 13
