Question

Mr frank has 1.08 kilograms of fertilizer for the plants in his nursery. He wants every plant to get 98 my of fertilizer 4 times each year. What is the number of plants he could fertilize with that amount? How much fertilizer will he have left over?

Answer 1

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;

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

-There are 2755 plants planted.

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

$Left=Total -Used\\\\=1080000\ mg-(2755\times98\times4)\\\\=40\ mg$

Hence, 40 mg of the fertilizer is left over.
