Answer:
Total cost= $60,800
Explanation:
Giving the following information: 
For 4,000 units:
Unitary variable cost= $8
Unitary fixed cost= $5
<u>First, we need to calculate the total fixed cost:</u>
Total fixed cost= 5*4,000= $20,000
<u>Now, we can determine the total cost for 5,100 units:</u>
Total cost= 5,100*8 + 20,000
Total cost= $60,800
 
        
             
        
        
        
Mike brought 100 shares costing $53 each.
Total costs of shares= 100*53
=$5300
He got dividends of $1.45 per share. A dividend is money that is earnt back from a share.
Total dividend amount = 1.45*100
=$145
I'm assuming that Mike sold his shares at the end of the year. He sells for $60 each.
Total sales amount=60*100
=$6000
The rate of return in this instance can be defined as the amount of money made back from a share. 
Rate of return= total earnings/ costs
Total costs= $5300
Total earnings=$6145
6145/5300=1.1594
=15.9%
Hope this helps! :)
        
             
        
        
        
Answer:
Explanation:
The partnership agreement is silent about the payment of salaries and the division of profits and losses.
Profits should be divided based on capital invested by each
The capital investment by Gillie, Taft and Dall is 60000 : 120000 : 60000 Distribution has to be in ratio of 1:2:1
Total profits are 120,000, 1:2:1 ratio
The distribution will be Gillie $30,000, Taft $60,000 and Dall $30,000. 
 
        
                    
             
        
        
        
Explanation:
Profit is maximized at the production point of four tops. The disparity in net income and net expenditure is highest in this amount.
Another way of talking about this is to note that for the first 4 shirts that Gilberto makes, the marginal cost (MC) of making each shirt is smaller than the total revenue (MR) it generates from selling the shirt.
Beyond just the third shirt he makes per hour, the total cost of making the shirt is higher than the amount Gilberto receives; thus, opting to manufacture more than 4 shirts decreases Darnell's benefit.
