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,

$\begin{gathered} x\ge\frac{100}{20} \\ x\ge5 \end{gathered}$

Hence, the inequality is

$x\ge5$
