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.

A

Step-by-step explanation:

I took the quiz and goodluck

A) x+y = 15

19x+8y = 164

Step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
