Constraints are simply the subjects of an objective function.
The inequality that represents the constraint is: 
Represent the number of hats with x, and the number of scarves with y.
From the question, we have:
- He spends 12 hours to knit a hat
- He spends 6 hours to knit a scarf
So, the equation of the total time spent is:

This time spent is not more than 20 hours.
So, the inequality is

Hence, the inequality that represents the constraint is:

A) Ms.Wright receive $12 as interest at the end of 1/2 year.
B) Ms.Wright receive $24 as interest at the end of 1 year.
Step-by-step explanation:
The sum deposited in the bank = Principle = $800
The rate of simple interest = 3%
The time = 6 months = (6/12) years = 0.5 years

So, here simple interest = $12.
So Ms.Wright receive $12 as interest at the end of 1/2 year.
B) Now here Time = 1 year
so, Simple interest = 
So Ms.Wright receive $24 as interest at the end of 1 year.
We can put it into one step by multiplying the cost by 1.07 which basically takes into account the old cost of the jacket and the tax
the expression is
original amount * decimal multiplier (1.07) = new amount
