Answer:
student ticket = $11
(adult ticket = $15)
Step-by-step explanation:
Let a = price of adult ticket
Let s = price of student ticket
Given:
- On the first night she sold 12 adult tickets and 11 student tickets for $301 dollars
⇒ 12a + 11s = 301
Given:
- On the second night she made $134 selling 6 adult tickets and 4 student tickets
⇒ 6a + 4s = 134
Multiply 6a + 4s + 134 by 2 then subtract from 12a + 11s = 301 to eliminate a:
⇒ (6a + 4s = 134) × 2: 12a + 8s = 268
12a + 11s = 301
- (12a + 8s = 268)
--------------------------
3s = 33
⇒ s = 33 ÷ 3 = 11
Substitute found value of s into one of the equations and solve for a:
⇒ 12a + 11(11) = 301
⇒ 12a + 121 = 301
⇒ 12a = 180
⇒ a = 15
Therefore, the price of an adult ticket is $15 and the price of a student ticket is $11
Answer:
a) 198.7% interest
Not too sure about answer to (b)
b) 4.75% annualized
Step-by-step explanation:
a) i used Interest = Principal x Rate x Time
40 = 525 x
x r
40 = 20.13r
r = 1.987 or 198.7%
b) i used this proportion:
=
'x' represents annualized rate
1/24 represents 2 weeks out of a year
1/24x = 1.98
x = 4.75%

Step-by-step explanation:
Let's call the smallest integer
n
. Then the next two consecutive integers are
n
+
1
and
n
+
2
.
"Sum of twice the smallest and 3 times the largest is 126"
2
(
n
)
+
3
(
n
+
2
)
=
126
2
n
+
3
n
+
6
=
126
5
n
+
6
=
126
5
n
=
120
n
=
24
So the smallest integer is
24
.
The three consecutive integers are then:
24
,
25
, and
26
.
