Answers
Given : Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water W=32-0.05n
To find : Capacity of glass tanks. Maximum marbles can be put in tank
Solution:
W = 32 - 0.05n
W = Water to be filled in Glass tank
n = Number of Marbles
if Andrea does not put any marble then water filled = Capacity of glass tank
=> n = 0
=> W = 32 - 0.05 * (0)
=> W = 32
Capacity of Glass Tank = 32 Litre
To fine maximum number of marbles
W ≥ 0
=> 32 - 0.05n ≥ 0
=> 640 - n ≥ 0
=> - n ≥ 640
=> n ≤ 640
Maximum Marbles can be put are less than 640
