Given
To find the inequality to show that, how much more needs to be saved to reach $100.
Now,
Let x be the amount saved in 1 day.
That implies,
The amount saved in 1 week
[tex]20x\ge100[/tex]
Then,
[tex]\begin{gathered} x\ge\frac{100}{20} \\ x\ge5 \end{gathered}[/tex]
Hence, the inequality is
[tex]x\ge5[/tex]
