Answer 2

Answer:

11. 112

12. The second deal is  better deal.

Step-by-step explanation:

11. If 5 books cost = 70$

    1 book will cost = (70 / 5)

                       70 divided by 5 = 14

    8 books will cost = (14 x 8)

 14 x 8=   112

Ans: 8 books will cost 112 $

12. If 6 eggs cost = 105 $

    1 egg will cost = (105 / 6)

                         105 divided by 6 = 17.5

         14 eggs cost = (17.5 x 14)

            17.5 x 14= 245

(Normally it would cost 245 but now it is for 216, which is better)

Ans: The better deal is the 14 eggs for 216$.
