Answer:

[tex]\textsf{Constraint 1}: \quad 15x+10y\geq 1850[/tex]

[tex]\textsf{Constraint 2}: \quad y \leq 5x[/tex]

[tex]\textsf{Constraint 3}: \quad y \geq 65[/tex]

Step-by-step explanation:

Inequality signs:

  • <  Less than.
  • ≤  Less than or equal to.
  • >  More than.
  • ≥  More than or equal to.

Given variables:

  • x = Number of lawns mowed.
  • y = Number of dogs walked.

Constraint 1

Given information:

  • $15 = Charge for mowing a lawn.
  • $10 = Charge for walking a dog.
  • $1850 = Minimum amount needed for the trip.

Therefore, the amount earned from mowing the lawns and walking dogs should be more than or equal to $1850:

[tex]\boxed{15x+10y\geq 1850}[/tex]

Constraint 2

Given information:

  • The number of dog walks that Sarah has scheduled is no more than 5 times the number of lawns Jacob has scheduled to mow:

Therefore, Sarah will walk less than or equal to 5 times the number of lawns mowed:

[tex]\boxed{y \leq 5x}[/tex]

Constraint 3

Given information:

  • Sarah will walk at least 65 dogs.

Therefore, Sarah will walk more than or equal to 65 dogs:

[tex]\boxed{y \geq 65}[/tex]
