The saline solution that you use to clean your lenses is on sale for $4.95 a bottle. You decide to stock up and buy 4
bottles. Use the distributive property to mentally calculate the
total cost of the 4 bottles of saline solution.

C) 113 1/4

Step-by-step explanation:When you do perimeter you do length plus length  plus width plus width.So the Length is 31 1/8  and  the width is 25 1/2 ,so you do 31 1/8 and add it to 31 1/8 which gives you 62.25 or 62 1/4 .Now you add  25 1/2 to  25 1/2 which gives you 51.After that you add 62 1/4 to 51 which gives you 113 1/4.

Hope it helps.
