Answer:

[tex]20x+10y\ge 2000[/tex]

Step-by-step explanation:

Let x represent the number of lawns Jacob mowed and y represent the number of dogs Sarah walked.

Jacob charges $20 each time he mows a lawn, then he earns $20x for x lawns mowed.

Sarah charges $10 each time she walks a dog, then she earns $10y for y dogs walked.

In total, they will earn $(20x + 10y). They need at least $2000 in order to go on a trip, then

[tex]20x+10y\ge 2000[/tex]

Note that [tex]x\ge 0,\ y\ge 0.[/tex]
