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;
-There are 2755 plants planted.
-We subtract the fertilizer used from the total to find what is left:
Hence, 40 mg of the fertilizer is left over.
