Answer:

-2755 plants

-40mg  is left.

Step-by-step explanation:

Given the fertilizer amount is 1.08kg, and the amount per plant per year is (4*98mg):

#convert the weight of the fertilizer into grams then divide by quantity per plant to determine number of plants;

[tex]Number \ of \ plants=\frac{Fertilizer \ Amount}{Quantity \ per \ plant}\\\\=\frac{1.08\times 1000000}{98\ mg\times 4}\\\\=2755.1\approx2755[/tex]

-There are 2755 plants planted.

-We subtract the fertilizer used from the total to find what is left:

[tex]Left=Total -Used\\\\=1080000\ mg-(2755\times98\times4)\\\\=40\ mg[/tex]

Hence, 40 mg of the fertilizer is left over.
