How many jars of nuts worth $4 per jar must be mixed with some nuts worth $6 per jar to get 50 jars of nuts worth $4.80 per jar

30 jars of nuts worth $4 per jar must be mixed with 20 jars of nuts worth $6 per jar

Step-by-step explanation:

Let

x ----> the number of jars of nuts worth $4

y ----> the number of jars of nuts worth $6

we know that

----> equation A

----> equation B

Solve the system by graphing

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (30,20)

see the attached figure

therefore

30 jars of nuts worth $4 per jar must be mixed with 20 jars of nuts worth $6 per jar

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
