Answer:
the value of c = 32.13 
Step-by-step explanation:
all you had to do was take one of the options and divide it by 2.1 and you'll know you have to right answer when it equals 15.3 but just remember if you are dividing by a smaller number the numerator has to be a bigger number to be able to equal whatever is on the other side of the equals symbol. 
sorry I'm bad at explaining but I hope this helps 
 
        
                    
             
        
        
        
Well,  since we know is a geometric sequence, we can always get the common ratio  of it by simply dividing one value by the one behind it... so let's do so, with say hmm -32 and 8  -32/8 = -4  <-- our common ratio
the first term is -2
 
 
        
        
        
Answer:
See explanation
Step-by-step explanation:
Consider the natural number 
If  is the natural number, then
 is the natural number, then  are next two natural numbers, so numbers
 are next two natural numbers, so numbers  and
 and  are three consecutive numbers.
 are three consecutive numbers.
Given three consecutive natural numbers, one of them is always even number and one of them is always multiple of 3, so the product 

is divisible by 6.
 
        
             
        
        
        
Dress: 93$ at 100-25%=75%
-> divide the marked down cost by the percentage to get the cost of a single percent and then multiply it with the markdown again to get the saved cost
93/75*25=93/3*1=31*1=31$
shoes 119$ at 100-15%=85%
119/85*15=119/17*3=7*3=21
add both savings together for the full sum: 31+21=52$
