From the given scenario above, the sum of x and y should be at most 600. That is presented in the inequality,
x + y ≤ 600
Then, for their income from the sales,
5x + 7y ≥ 3500
We solve the values of x and y in the system of inequalities by substituting first equal sign to both symbols, giving us with values of x and y equal to 350 and 250, respectively.
