Say he needs to mow 'x' no of lawns to go on trip,

<u>So money he will get by mowing lawn</u>

=$20x

which is the amount of money he needs

(=$125)

But he already has $45.

So,

$125-$45=$80 is the amount of money he will require just to go trip.

i.e. ,

➧20x ⩽80

which is the required inequality.

<u>Divide both sides by 20,</u>

<h3>➧x⩽4</h3>

<u>which means he needs to mow </u><u>4</u><u> lawns to go on trip.</u>
