The cost of an adult ticket is $15.50 and the cost of a child ticket is $8.50
Proof:
Set up a system of equations calling Adults a and Children c
2a+3c= $56.50 (equation 1)
4c+a= $49.50 (equation 2)
a= -4c+49.50 (i subtracted 4c to both sides) (label equation 3)
sub equation 3 into equation 1
2(-4c+49.50)+3c= 56.50
-8c+99+3c=56.50
-5c+99=56.50
-99 -99
-5c = -42.50
c= -42.50/ -5
c= 8.50
sub c=8.50 into equation 3 to find adult price
a= -4(8.5)+49.50
a= 15.50
Therefore Child Cost = $8.50 and Adult Cost= $15.50
Answer:
C.) 217
Step-by-step explanation:
If the top 4% of athletes are allowed to be part of the team, then the bottom
will not qualify.
We look for a z-score below which
of the population lie.
Reading from the z-table as shown in the attachment, this z-value corresponds to
.
We now use the z-score formula to find the required minimum qualifying score.

where 
We substitute and solve for x.





The correct choice is C
Step-by-step explanation:
Set up a proportion.
1489.64/x=39/100
(X stands for the whole)
once you solve, x is equal to 148694/39, 3819 23/39, or about 3819.589744
