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

-2755 plants

-40mg is left.

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=(Fertilizer \ Amount)/(Quantity \ per \ plant)\\\\=(1.08* 1000000)/(98\ mg* 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*98*4)\\\\=40\ mg`

Hence, 40 mg of the fertilizer is left over.
