On a trip, the fare was 50¢ for each adult and 25¢ for each child. If 30 passengers paid $12.25, how many adults and
2 answers:
<u>Answer: </u>
The number of adult is 19 and number of children is 11
<u>Solution: </u>
Given that there were total 30 passengers.
Let the number of adult be x.
Therefore, number of children = 30-x
It is given that the fare for adult = 50$
The fare for x adults will be
It is also given that the fare for children is 25$
The fare for (30-x) children =
Now according to the question, 30 passengers paid $1225
50x + 25(30-x) = 1225
50x + 750 - 25x = 1225
25x = 1225-750
25x = 475
x = 19
Therefore number of adult = 19
Number of children = 30-19 = 11
From the given below equations, 25x + 50x = 30(1225) cannot be used to solve the problem.

Answer:
<u>Properties that are present are </u>
Property I
Property IV
Step-by-step explanation:
The function given is where b > 1
Let's take a function, for example,
Let's check the conditions:
I. As the x-values increase, the y-values increase.
Let's put some values:
y = 2 ^ 1
y = 2
and
y = 2 ^ 2
y = 4
So this is TRUE.
II. The point (1,0) exists in the table.
Let's put 1 into x and see if it gives us 0
y = 2 ^ 1
y = 2
So this is FALSE.
III. As the x-value increase, the y-value decrease.
We have already seen that as x increase, y also increase in part I.
So this is FALSE.
IV. as the x value decrease the y values decrease approaching a singular value.
THe exponential function of this form NEVER goes to 0 and is NEVER negative. So as x decreases, y also decrease and approached a value (that is 0) but never becomes 0.
This is TRUE.
Option I and Option IV are true.
