The hypothetical cell will approximately contain 94 percent (94%) of water.
If a cell is placed in a hypertonic solution that contains more concentration of solutes (such as salt and glucose) than the cell, then it will shrink because water moves outside the cell.
If a cell is placed in a hypotonic solution that contains more concentration of water than the cell, then the water will move inside the cell.
Finally, if a cell is placed in an isotonic solution, which contains the same concentration of solute and solvent as outside the cell, there will be no change in the cell and the solution.
In this case, the percentage of solutes is equal to 5% (glucose) + 1% (salt) = 6%, so the remmaining porcentage of water is equal to 94 percent (94%).
Boyle's Law explains the relationship between volume and pressure. According to Boyle's Law, the volume of a fixed amount of gas decreases as its pressure increases. If the volume increases, its pressure decreases.
