Respuesta :
x = amount of lawns
y = amount of dog walks
25x + 15y = 1975
25x + 15(50) = 1975
25x + 750 = 1975
25x = 1225
x = 49
so x ≤ 49 (this number depends on how much Sarah walks)
y ≥ 50 (is how much Sarah walks)
hope this helps

jacobmoney+sarahmoney=totalmoney
totalmoney≥1975 so they can go
so jacobmoney+sarahmoney≥1975
find each
jacobmoney=lawn money=number of lawns mowed times cost per lawn=x times 25=25x
sarahmoney=dogmoney=number of dogs walked times cost per dog walk=y times 15=15y
so therfor
25x+15y≥1975
additionally, number of dog walks that sarah does is no mroea than 4 times number of lawns mowed, means y≤4x
and sarah will walk at least 50 dogs
y≥50
the constraints are
25x+15y≥1975
y≤4x
y≥50
