Answer:
c=0.02(m)+30(5)
or 
c= 150+0.02(m)
or 
c=0.02(m)+150
or 
c=30(5)+0.02(m)
Step-by-step explanation:
This is because c, or cost is equal to 30 dollars a day as a base fee or 150 total for five days plus 0.02 per mile. So, if you multiple the mileage driven by 0.02 and add 150 for the 30$ per day at 5 days. This is your equation 
These are just different ways you could write that since it is clear you have a multiple choice question 
 
        
             
        
        
        
AnsweTo see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.r:

There are a lot of things that are equivalent to 16/81.
16/81 = 0.197530864
Or we can keep multiplying 2 to the numerator and denominator:
16/81 = 32/162 = 64/324 = 128/648
