H shows the ratio of pencils to pens sold at the school bookstore. If the bookstore sells 15 pencils, what is the ratio of pencils to pens sold written as a fraction?

Step-by-step explanation:

See attachment for complete question.

We start by solving for the equation of the graph (The graph shows a linear equation)

Represent pencils with x and pen with y

From the graph, we have that:

Solve for slope (m)

The equation is calculated using:

Where

Add 4 to both sides

Now, to the question.

When pencils is 15 implies that

Solving for x, we have:

i.e. Pen = 10

Ratio = x ; y

Convert to fraction

Simplify

Hence,

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
