Answer:

Sorry, I don't know exactly what an inequality is but he needs to mow 4 lawns.

Step-by-step explanation:

$125-$45=80

$20x?=$80

?=4

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

So money he will get by mowing lawn

=$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.

Divide both sides by 20,

➧x⩽4

which means he needs to mow 4 lawns to go on trip.
