Write a set of constraints to model the problem, with x representing the number of lawns mowed and y representing the number of dogs walked. 
Be sure to include: (1) an inequality to represent the amount that Jacob and Sarah must earn to pay for the trip, (2) the constraint that compares the number of dogs to the number of lawns, (3) the constraint to represent the least number of dogs Sarah could walk

representing the number of lawns mowed.
 y representing the number of dogs walked. 
They need at least $1975 means less than or equal to 1975.
Hence, $$x+y \le1975$$
