A cooking group made 240 oz of spaghetti sauce to sell at a county fair. The group can pour the sauce into small jars that hold 8 oz and large jars that hold 16 oz. The group leader made a sketch to show the line representing the different combinations of jar sizes the group can use. The x-axis represented the number of small jars and the y-axis represented the number of large jars. The group leader labeled only the intercepts.

Question

Which points did the group leader label?

Answer 1

To determine the intercepts, we can set up the following equation for the total amount of spaghetti sauce using small jars (8 oz) and large jars (16 oz):

Let:

• $x$ = number of small jars
• $y$ = number of large jars

The equation representing the total amount of sauce is:

$$8x+16y=240$$

To find the intercepts:

1. Find the x-intercept: Set $y=0$:

$$8x+16(0)=2408x=240x=\frac{240}{8}=30$$

So, the x-intercept is $(30,0)$.

2. Find the y-intercept: Set $x=0$:

$$8(0)+16y=24016y=240y=\frac{240}{16}=15$$

So, the y-intercept is $(0,15)$.

The intercepts labeled by the group leader are $(0,15)$ and $(30,0)$.

Therefore, the correct response is:

(0, 15) and (30, 0).
