PLEASE HELP!!!!! Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance t icket and one same-day ticket is $75. For one performance, 20 advance tickets and 35 same-day tickets were sold. The total amount paid for the tickets was $2100. What was the price of each kind of ticket?
1 answer:
Answer:
The answer to your question is Advance = $35 and same-day = $40
Step-by-step explanation:
Advanced = a
Same-day = s
Equations
a + s = 75 ----- (I)
20a + 35s = 2100 ----- (II)
Process
1.- Solve the equations by elimination.
Multiply equation I by -20
-20a - 20s = -1500
20a + 35s = 2100
Simplify
0 + 15s = 600
Solve for s s = 600/15
s = $ 40
Substitute "s" in equation I to find "a"
a + 40 = 75
Solve for a
a = 75 - 40
a = 35

Answer:
87.9
Step-by-step explanation:
Use a calculator or table to find the z-score that corresponds to 25%.
P(Z < z) = 0.25
z = -0.675
Now find the value that corresponds to that z score.
z = (x − μ) / σ
-0.675 = (x − 101.3) / 19.9
x = 87.9
