A because they are parallel and equal
X-1/2=15 1/4
15 1/4 = 15*4 + 1 = 61/4
61/4
x - 1/2 = 61/4
+1/2 +1/2
61/4 + 2/4 = 63/4
x = 63/4
Answer:
10.75
Step-by-step explanation:
The cost of an adult ticket is £6 more than that of a child ticket, so will be shown by c+6.
Now, we are told that the cost of four child tickets and two adult tickets is £40.50, so we can put this in an equation and solve for c:
(c+6)+(c+6)+c+c+c+c=40.50
6c+12=40.50
6c=28.50
c=4.75
so, a childs ticket is 4.75
now to find the cost of an adult ticket you add 6,
4.75 + 6
= 10.75
