Answer:

Jerome bought 15 videos from a department store. Some videos were new releases, x,  which cost $19, and some videos were classics, y, which cost $8. He spent a total of $164 on the videos. Which system of equations is set up correctly to model this information?

x + y = 15. 19 x + 8 y = 164.

x + y = 15. 8 x + 19 y = 164.

x + y = 164. 19 x + 8 y = 15.

x + y = 15. 19 x minus 8 y = 164.

ANSWER IS A

Answer:

The system of equations is

x+y=15

19x+8y=164

Step-by-step explanation:

Let

x------> the number of videos of new releases

y-----> the number of classics videos

we know that

x+y=15 ------> equation A

19x+8y=164 ------> equation B

Using a graphing tool

Solve the system of equations

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (4,11)

see the attached figure

therefore

the number of videos of new releases is 4

the number of classics videos is 11
