Question

Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water. W represents the volume of water Andrei uses ( in liters) if he uses n marbles. W=32-0.05n What is the glass tanks volume?

Answer 1

Volume of marbles + Volume of water = Volume of the tank

Volume of water = Volume of the tank - Volume of marbles

The given equation is:

W = 32 - 0.05n

where W is the Volume of water, in liters. Then, 32 liters is the volume of the tank, and 0.05n is the volume of the marbles, in liters
