Complete question :
Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water.W(n) models
the amount of water Andrei uses (in litres) if he uses n marbles:W=32-0.05n.
What is the glass tank's volume
Answer: 32 liters
Step-by-step explanation:
The volume of the glass tank:
W = 32 + 0.05n
W represents the volume of water that will be added to the marble to fill the glass tank.
HERE the volume of marble is represented by 0.05n portion of the equation, where n is the number of marbles.
Therefore, the equation could be rewritten as :
Volume of water = W
Volume of marble = 0.05n
The addition of both give s the entire volume of the glass tank.
W = 32 - 0.05n
W + 0.05n = 32
Therefore, volume of glass tank = 32
