Question

I need to know the answer to the top one

Answer 1

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

`20x\ge100`

Then,

`\begin{gathered} x\ge(100)/(20) \\ x\ge5 \end{gathered}`

Hence, the inequality is

`x\ge5`
