Answer/Step-by-step explanation:
Since there is a proportional relationship between amount of seed a landscaper uses and the area of lawn covered, therefore: constant of proportionality = area covered / seed.
The constant of proportionality would be same for all pairs of values given in the table.
Thus:
[tex] \frac{75}{3} = \frac{25}{1} = 25 [/tex]
[tex] \frac{100}{4} = \frac{25}{1} = 25 [/tex]
