Answer:

Step-by-step explanation:
 A exponential function is represented by

where a is the vertical stretch and b is the base and x is the nth 
power of x
 
Since the first number corresponds with zero, that means our y intercept is the first number.
This means when x=0 , y=5 so let find the value of 5.

b to the 0th power equal 1 so


Our equation is for now

Now let plug in 1,30

Divide 5 by both sides

Anything to the 1st power is itself so b equal 6.
So our equation is 

 
        
             
        
        
        
Answer:
- the total installment is  $936
-  the carrying charges are $186
- the monthly rate to buy the items are  19.23 or 20 months
Step-by-step explanation:
$39 for 24 months comes to ...
$39 × 24 = $936
The "carrying charges" are the difference between the cash price and the installment price:
 $936 -750 = $186
  Saving at the rate of $39 per month, it would take ...
   $750/$39 = 19.23 months  
about 20 months to save up the cash price.
Often, such savings would come from a once-a-month paycheck, so it would take more than 19 such paychecks to save the required amount.
hope it will help :)
