Answer:
He can fertilize 2755 plants and have 40 mg of fertilizer left over
Step-by-step explanation:
First figure out how much each plant will require per year
98 mg * 4
392 mg
We need to change 1.08 kg to mg
There are 1000 g per kg and 1000 mg per g
1.08 kg * 1000g/kg * 1000mg/g =1080000 mg
Divide 1080000mg by 392 mg per plant per year
1080000/392 =2755.102041
He can fertilize 2755 plants
2755 * 392 =1079960
1080000-1709960=40
He can fertilize 2755 plants and have 40 mg of fertilizer left over
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*100000}{98mg*4} \\2755.1= 2755\\There are 2755 plants planted\\We subtract the fertilizer used from the total to find what is left:\\Left=total-used \\1080000mg-(2755*98*4) = 40mg\\Hence, 40 mg of the fertilizer is left over.[/tex]
