His co-payment for his physician visits would be: 
10 x 18 = $180.
His co-payment for his physical therapy would be:
10 x 20% x 150= $300.
You then have to add both co-payments which give you $480.
 
        
             
        
        
        
Answer:
C
Step-by-step explanation:
An approximation of an integral is given by: 

First, find Δx. Our a = 2 and b = 8: 

The left endpoint is modeled with:

And the right endpoint is modeled with: 

Since we are using a Left Riemann Sum, we will use the first equation. 
Our function is: 

Therefore: 

By substitution: 

Putting it all together: 

Thus, our answer is C. 
*Note: Not sure why they placed the exponent outside the cosine. Perhaps it was a typo. But C will most likely be the correct answer regardless. 
 
        
             
        
        
        
Add the gain and the last weight together
new weight = 6 3/4 + 1 1/2
or we can write it as
new weight = 6 + 3/4 + 1 + 1/2
Separate whole numbers and fraction
new weight = 6 + 3/4 + 1 + 1/2
new weight = 6 + 1 + 3/4 + 1/2
Simplify the whole numbers
new weight = 6 + 1 + 3/4 + 1/2
new weight = 7 + 3/4 + 1/2
Equalize the denominators of the fraction
new weight = 7 + 3/4 + 1/2
new weight = 7 + 3/4 + 2/4
new weight = 7 + 5/4
Because 5/4 is improper fraction, change it to mixed fraction
new weight = 7 + 5/4
new weight = 7 + 1 1/4
new weight = 7 + 1 + 1/4
new weight = 8 + 1/4
new weight = 8 1/4
