Answer 2

Answer:

The required inequality would be 0.5h ≥ 25

Explanation:

Given,

The earning for 1 hour = $ 10,

So, the earning for h hours = 10h dollars,

If she saves 5% of her earning in saving,

Then her saving after h hours = 5% of 10h

$=\frac{5\times 10h}{100}$

= 0.5h

According to the question,

Her saving ≥ 25 dollars

⇒ 0.5h ≥ 25

Which is the required inequality.
