Answer:
The answer is not complete. I will explain the concept of profit to you.
Step-by-step explanation:
We can determine profit deducting direct costs (cost price) of commodities from sales (selling prices) of the commodities.
Profit = Selling Price - Cost Price
Example:
A trader buys some dresses for #2,500 in May and agrees to pay for it in three months’ time. He sells off all the dresses in August for #4,500. The profit for the month is #2,000.
The formula for percentage profit is 
The formula for gross profit is Revenue – Cost of Sold Items
Profit Margin = 
* 100
While Gross Profit Margin can be calculated as 
* 100
Any of these formulas can be used to calculate profit-related questions.

Answer:
Step-by-step explanation:
We know that A and B are complementary angles. So, they must add up to 90°. As an equation:
Since we know their equations, substitute:
Solve for x. Combine like terms on the left:
Subtract 9 from both sides:
Divide both sides by 9:
So, the value of x is 9.
We want to find A. So, let's use the equation for A:
Substitute 9 for x:
Add:
So, the measure of A is 17°.
Answer:
He paid $253.09 in interest.
Step-by-step explanation:
To find how much did he pay in interest, we use the simple intrest formula, that is given by:
In which I is the value paid in interest, P is the money borrowed, r is the yearly interest rate and t is the time.
In our problem, we have that:
He borrowed $4,400, so 
At 4.75% yearly. We measure the time in days, so we have to divide this value by 365. So 
.
From December 26, 2019 to February 21, 2021, there are 422 days, so 
.
He paid $253.09 in interest.
