The circle graph or the pie graph below shows the amount of sales from different booth
Use the graph to illustrate the problem
Total Sales=
₱ 6.588
As you can see the portion or sector for the ice cream parlor is ¼ or 25% of the whole graph. So get ¼ or 25%of
₱ 6.588
The second question was about the total sales of the souvernir items booth. To find the answer for this question add all the sales from food, drinks and ice cream then substract the sum for the total sales
STEP 3
For Question #1
¼ 0f 6588 = 1647
Or
25% 0f 6588
=0.25 x 6588
=1647
For Question #2
Drinks =
₱1580
Food =
₱2297
Ice Cream =
₱1647
Solution for Question #2
1580 + 2297 + 1647
= 5524

b. 6588 - 5524
= 1064
The ice ceram parlor had a total sales
₱1647
The souvernir items booth had a total sales
₱1064
