i created this table in desmos and then entered this equation underneath:
y₁ (tilda sign) = mx₁ + b
desmos will draw a line of best fit and provide the correlation coefficient, slope, and y-intercept
 
        
             
        
        
        
Answer:  $499.00
<u>Step-by-step explanation:</u>
Wholesale cost + (20% of Wholesale cost) = Selling price
--> 1.20 × Wholesale cost = Selling price
Let x represent the Wholesale cost
  1.2x = 598.80
<u>÷1.2  </u>    <u>÷ 1.2      </u>
      x = 499.00
 
        
             
        
        
        
From right triangle trigonometry, we have the following:

, 
where the "opposite side" means the opposite side to angle with measure 

, and "adjacent side" means the adjacent side to angle with measure 

.

 is a constant which can be found using a calculator.
In the calculator of the pc press: view - scientific - 35 - tan.
 This gives 

Thus, back in the equation 

 we substitute as follows and solve:

Quotients can sometimes be irrational so it is necessary to estimate them, products on the other hand are only rational, provided they aren't multiplied by an irrational, so it is not necessary to estimate
