Answer: Children tickets cost 7.50
Adult tickets cost 12.50
Step-by-step explanation:
Let a represent adult tickets
Let c represent child tickets
On the first day she sells 6 adult tickets and 5 children tickets for total of 112.50. This can be written as:
6a + 5c = 112.50 ...... equation i
On the second day she sells 8 adult tickets and 4 children tickets for the total 130. This can be written as:
8a + 4c = 130 ....... equation ii
6a + 5c = 112.50 ...... equation i
8a + 4c = 130 ....... equation ii
Multiply equation i by 4
Multiply equation ii by 5
24a + 20c = 450 ........ equation iii
40a + 20c = 650 ......... equation iv
Subtract iii from iv
16a = 200
a = 200/16
a = 12.50
Adult tickets cost 12.50
From equation ii,
8a + 4c = 130 
8(12.50) + 4c = 130
100 + 4c = 130
4c = 130 - 100
4c = 30
c = 30/4
c = 7.50
Children tickets cost 7.50

Step-by-step explanation:
From the figure,
Radius matches with (F) that is a segment between the centre of a circle and a point on the circle.
Arc matches with (D) that is Circle A and the portion of the circle between points B and C is darkened.
Chord matches with (C) Circle A and a line segment connecting points B and C which are on the circle.
Secant matches with (E) that is Circle A and a line segment connecting points B and C which are on the circle.
Tangent matches with (A) that is a line intersects a circle in exactly one point.
Circumference matches (B) that is the distance around a circle.
 
        
                    
             
        
        
        
64 + 5 = 69
69 + 64 = 133 cupcakes
