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
Since a quantity is a variable that could be described in terms of numbers, then the quantities that can be measured exactly be integers would be, say, the amount of houses to be supplied with power and the number of people in the household. A fraction could never be a possible amount, because a person and a house is counted as one whole.
