ANSWER
C. Both equations will find the correct solution.
EXPLANATION
It was given in the question that, Asha and Jamal started with 45 plants.
We were told that, they sold some plants and now they have 21 plants left.
Let
represent the number of plants sold.
Then when we add the number of plants sold and the number left, we should get 45.
This implies that,
This is Jamal's equation.
On the other hand, if we subtract the number of plants sold from the total number of plants, we should get 21. Thus,
This is Asha's equation.
The two equations are therefore equivalent.
They will give the same solution.
The correct answer is C.

Answer:
$2400 in A rated bond and $3000 in B rated bond.
Step-by-step explanation:
We have been given that Maria has recently retired and requested an extra $444.00 per year in income.
We can represent this information in an equation as:
She has $5400 to invest in an A-rated bond that pays 10% per annum or a B-rated bond paying 6% per annum.
From equation (1), we will get:
Substitute this value in equation (2):
Therefore, Maria should invest $2400 in A-rated bond.
Substitute in equation (1):
Therefore, Maria should invest $3000 in B-rated bond.
