My answer:
They need at least $1975. Jacob charges $25 each time he mows a lawn and Sarah charges $15 each time she walks a dog.
25x + 15y ≥ 1975
The number of dog walks that Sarah has scheduled is no more than four times the number of lawns Jacob has scheduled to mow.
632=.60 x (it is important to convert the percentage to decimal by dividing by 100) 632/.60=x x= 1053.33 x is your original price the actual answer is 1053.3333(3 repeating) but since it is money you cut it off at 2 decimal points.
