Well, we know that 2/3 is about equal to .666 and 2/4 equals .5 Since .666 is a greater number, Ricardo read more.
A) because it is 2/3 past 1
The first thing you should know is that you need three points to be able to graph a second degree equation.
You can create a table and plot several points to obtain the parabola
In this case we will use a computational tool called wolfram alpha
Answer:
See attached image.
The graph is shown for two different intervals of the domain.
The number of adults = 41
The number of children = 97
Step-by-step explanation:
Let x be the number of adults and
y be the number of children
then according to the given conditions

From equation 1:
x = 138-y
Putting in equation 2

Dividing both sides by -7

Putting y = 97 in equation 1

Hence,
The number of adults = 41
The number of children = 97
