Answer:
Given below
Step-by-step explanation:
y = 4 , m = -1 , x = 2
y = mx + b
4 = -1 (2) + b
4 = -2 + b
6 = b
0.4L = 400ml
Each student effectively adds 10ml of water so 22 students are adding 10ml of water each. Therefore, 22 x 10 = 220ml total in all the containers added by all 22 students
Water left = 400 - 220 = 180
The answer is B.
C I think because all of them add up to it so it would be 5seconds
