Sharon earns $25 per item. This means that this number is increasing with each item sold, then you will have a variable with this number, such as 'x'.
Plus a base salary of $100 per week. This means that this number is always true for each week and will not change when looking at a weekly perspective.
How many items must she sell to earn at least $700 per week. This is the end goal or even slightly over $700.
To set it up:
25x + 100 ≥ 700
To solve:
25 x + 100 ≥ 700
- 100 -100
______________
25x ≥ 600
___ ___
25 25
_______________
x ≥ 24
Interpret:
Sharon must sell at least 24 items.
Fomented means encouraged/excited state.
Therefore, our answer is encouraged.
Answer:
a. 300 Kg of fertilizer
b. 225 Kg of fertilizer
c. 400 Kg of fertilizer
d. 600 Kg of fertilizer
Explanation:
The percentage composition ratio of Nitrogen, Phosphorus and Potassium in a 1 Kg bag of the given fertilizer is 40:15:10.
Therefore a 1 Kg bag contains;
40/100 * 1 Kg = 0.4 Kg of Nitrogen;
15/100 * 1 Kg = 0.15 Kg of phosphorus;
10/100 * 1 Kg = 0.1 Kg of potassium
Quantity of fertilizer required to add to a hectare to supply;
a. Nitrogen at 120 kg/ha = 120/0.4 = 300 Kg of fertilizer
b.. Nitrogen at 90 Kg/ha = 90/0.4 = 225 Kg of fertilizer
c. Phosphorus at a rate of 60 kg/ha = 60/0.15 = 400 Kg of fertilizer
d. Potassium at a rate of 60 kg/ha = 60/0.1 = 600 Kg of fertilizer
