Answer:
C. y = 11000(1.086)^7
Explanation:
Given the following data;
Principal = $11,000
Interest rate = 8.6% = 8.6/100 = 0.086
Time = 7 years
To derive a mathematical expression, we would use the compound interest formula;
 
 
Where;
A is the future value. 
P is the principal or starting amount. 
r is annual interest rate. 
t is the number of years for the compound interest. 
Substituting into the formula, we have;
 
 
 
 
 
 
 
 
A = $19,580
 
        
             
        
        
        
1. What is the variable overhead spending variance? (HINT: The answer $980 unfavorable, but I need work to support this)
2. What is the variable overhead efficiency variance? (HINT: The answer is $4,040 unfavorable, but I need work to support this)
        
             
        
        
        
Answer:
total = total + amount
Explanation:
The statement that increments total by the value associated with amount i.e add the value associated with amount to that associated with total and assign the result to total is:
total = total + amount
