The manager of a music store ordered 20 new violins. she ordered some of two different models: the standard and the deluxe. each standard violin costs $500, and each deluxe violin costs $800. if the manager spent exactly $11,500 on these violins, how many deluxe violins did she order?

5 deluxe violins and 15 standard violins

Step-by-step explanation:

5 x 800 = 4,000

(That was for deluxe violins' price all together ^)

and...

15 x 500 = 7,500

(That was for standard violins' price all together)

4,000 + 7,500 = 11,500

∴ 5 deluxe violins and 15standard violins to fit the question rules!

Hope this helps :]

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

w'x is 0.

hope it
