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 :]

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
