Answer:


Step-by-step explanation:
Let the quotient be represented by 'Q'.
Given:
The difference of a number 'y' and 16 is 
Quotient is the answer that we get on dividing two terms. Here, the first term is 40 and the second term is  . So, we divide both these terms to get an expression for 'Q'.
. So, we divide both these terms to get an expression for 'Q'. 
The quotient of 40 and  is given as:
 is given as:

Now, we need to find the quotient when  . Plug in 20 for 'y' in the above expression and evaluate the quotient 'Q'. This gives,
. Plug in 20 for 'y' in the above expression and evaluate the quotient 'Q'. This gives, 

Therefore, the quotient is 10, when the value of 'y' is 20.

8. coupons offer deals upfront, rebates only offer them after purchase, and sales are short times to drive sales
Step-by-step explanation:
7 work. best buy: 60 - 2 = 40     40 x 4 = 160
          Gamestop: 60 x 0.3 = 18   42 x 4 = 168
                             160 - 168 = -8

Answer:
The value of first coin will be $151.51 more than second coin in 15 years.
Step-by-step explanation:
You have just purchased two coins at a price of $670 each.
You believe that first coin's value will increase at a rate of 7.1% and second coin's value 6.5% per year. 
We have to calculate the first coin's value after 15 years by using the formula 

Where A = Future value
            P = Present value
            r = rate of interest
            n = time in years
Now we put the values 



A = (670)(2.797964)
A = 1874.635622 ≈ $1874.64
Now we will calculate the value of second coin.



A = 670 × 2.571841
A = $1723.13
The difference of the value after 15 years = 1874.64 - 1723.13 = $151.51
The value of first coin will be $151.51 more than second coin in 15 years.
