The function for the condition given in the question is: y = 10xm, here x is number of minutes and y is total price. The graph of the function is attached.
What is graph?
The link between two or more sets of numbers or measures is depicted mathematically in a graph.
Let the number of minutes be x, and
The total price be y cents.
As given in the question, the price is 10 cents per minute.
Therefore, the function made out of this is: y = 10x
NOTE: The negative part of the graph can be ignored as time can't be negative

Answer:
Step-by-step explanation:
we know that
The probability that a point chosen randomly inside the rectangle is in the triangle is equal to divide the area of the triangle by the area of rectangle
Let
x-----> the area of triangle
y----> the area of rectangle
P -----> the probability
<em>Find the area of triangle (x)</em>
<em>Find the area of rectangle (y)</em>
<em>Find the probability P</em>
