Question

It’s homework please help. Here is the graph. I’ll send tutor a picture of the question that goes along with the chart.

Answer 1

24 cents is the correct answer

Answer 2

a) 24 cents

b) 24

Step-by-step explanation

a) We want to find out how the cost of chesse increases for every ounce.

To do that, we need to simply find the slope of the graph.

This is because the slope is the rate of change (increase or decrease) in the y values (cost) with resepct to the x values (weight).

In other words, slope of this graph is how much cheese costs per ounce.

The formula for slope is:

`\text{slope = }(y_2-y_1)/(x_2-x_1)`

From the graph we have to pick two sets of points.

Let us pick:

(x1, y1) = (1, 24)

(x2, y2) = (3, 72)

So, the slope is:

`\begin{gathered} \text{slope = }\frac{72\text{ - 24}}{3\text{ - 1}} \\ \text{slope = }(48)/(2) \\ \text{slope = 24 cents per ounce} \end{gathered}`

This means that for every ounce, the price increases by 24 cents

b) As calculated above, we see that the slope of the graph is 24 cents/ounce
