2
3
4
5
Price (dollars) y
22
33
44
55

Brand B:

How many dollars more is the price of 8 bottles of Brand B than the price of 8 bottles of Brand A oil?

Answer 1

the answer is 48 dollars more

Answer 2

Answer:

The number of dollars more is the price of 8 bottles of Brand B than the price of 8 bottles of Brand A oil is:

                        $   48

Step-by-step explanation:

Brand A--

Number of bottles (x)       Price (dollars) y

2                                                   22

3                                                   33

4                                                   44

5                                                   55

The function that represents the relation between the price of the bottles and the number of bottles is:

               y=11x

Brand B--

Also, the price of the bottles depending on the number of bottles is:

                 Y=17x  

According to Brand A the price of 8 bottles is:   y=11×8=$ 88

and according to Brand B the price of 8 bottles is: y=17×8= $ 136

Also, the difference in the price of Brand B to that of Brand A for 8 bottles is:

       $ 136-$ 88

    = $ 48
