Answer:
To maximize return, A with 390000 and B with 210000
Step-by-step explanation:
Given that a financier plans to invest up to $600,000 in two projects
Let x be the amount invested in 8% and y in 16%
Other information given is the investment in project B is riskier than the investment in project A, she has decided that the investment in project B should not exceed 35% of the total investment.
i,.e. 
Also 
The objective is to maximize interest function

subject to the above two constraints.
The corner points would be P(390000,210000) or Q(600000,0)
Calculate Z for these two points
Profit at P = 
Profit at Q = 
So to maximize return, A with 390000 and B with 210000
I would go with option D)
since,
It is A because opposite of angle 27 degrees is the same angle if you see
Answer:
$1500
Step-by-step explanation:
It is given that
Rent = $100
Groceries and drinks = $1000
Insurance premiums = $10
Loan interest payment =$30
Clothes = $200
Utilities = $300
Home security fee = $200
Fixed cost are costs that does not vary and variable cost are costs that vary with goods and services.
In the given problem, rent , insurance premiums, loans interest payment ad home security fee are fixed cost.
Groceries and drinks, clothes and utilities are variable cost.
So, total variable cost for last month is
Therefore, total variable cost for last month is $1500.
