Answer: $130.50
Step-by-step explanation:
2.5 hours= $25 an hour
 25+25+12.50=$62.50
Muffler=$65
65plus62.50
Total= $130.50
 
        
             
        
        
        
In fix fraction it will be, 1 7/8 
and the exact answer is 15/8
and in decimal from it will be, 1.875
 
        
                    
             
        
        
        
Answer:
An explicit representation for the nth term of the sequence:

It means, option (B) should be true.
Step-by-step explanation:
Given the geometric sequence

A geometric sequence has a constant ratio, denoted by 'r', and is defined by 

Determining the common ratios of all the adjacent terms

As the ratio is the same, so
r = 4
Given that f₁ = -1/2
substituting r = 4, and f₁ = -1/2 in the nth term


Thus, an explicit representation for the nth term of the sequence:

It means, option (B) should be true.
