Answer:
The correct option is D.
Explanation:
The given graph shows the relationship between shopping day preferences and percent of customers.
From the graph it is clear that
Sunday = 25%
Monday = 6%
Tuesday = 4%
Wednesday = 7%
Thursday = 18%
Friday = 10
Saturday = 30%
We have to find the percentage of customers prefers to shop on Saturday and Sunday.
![25+30=55](https://img.qammunity.org/2019/formulas/mathematics/college/pd0631nd6e082zv5m3qciqf6mpf12567s5.png)
