Answer: The total change in the volume of the water in the bowl after two days is decreased by [tex]\frac{13}{8}[/tex]
And the number must be negative as it is decreased by this amount.i.e.
[tex]\frac{-13}{8}\ cups[/tex]
Step-by-step explanation:
Since we have given that
Let the amount of water be 'x'.
On Tuesday, the water level decreases by [tex]\frac{7}{8}\ cup[/tex]
So, it becomes,
[tex]x-\frac{7}{8}[/tex]
On Wednesday, the water level decreases by [tex]\frac{3}{4}\ cup[/tex]
So, it becomes,
[tex]x-\frac{7}{8}-\frac{3}{4}\\\\=x+\frac{-7-6}{8}\\\\=x-\frac{13}{8}[/tex]
Hence, the total change in the volume of the water in the bowl after two days is decreased by [tex]\frac{13}{8}[/tex]
And the number must be negative as it is decreased by this amount.i.e.
[tex]\frac{-13}{8}\ cups[/tex]
