Answer:
P is represented by number -1.5.
Step-by-step explanation:
Given:
Number P on number line.
To find the number that is represented by P.
Solution:
In order to identify the number represented by P, we will trace the location of P on the number line.
The number line represents units from -5 to 5 to the nearest 0.5 units.
From the number line, we can see that P lies between -1 and -2.
<em>Since, the number line represents to the nearest 0.5 units so we we add 0.5 to the left number or subtract 0.5 units from the right number.</em>
So P can be given as :
⇒
Or
⇒
Thus, P is represented by number -1.5.
Admission to the zoo costs $15 per person.
The graph y = 15x correctly represents the total cost for a group to visit the zoo.
Given;
Admission to the zoo costs per person = $15
Let:
The total number of people visiting the zoo = x
The total cost for a group to visit the zoo = y
So, y ∝ x
y = 15x
Therefore, the graph y = 15x correctly represents the total cost for a group to visit the zoo.
