Can someone help me with this and explain please
Artyom0805 [142]
X/y = 2 so x = 2y
z/x = 4 so z = 4x but x = 2y so z = 4(2y) = 8y

now you have
x = 2y, z = 8y 

x + y + z          2y  + y + 8y             11y              11
------------ = -----------------------= ------------- =   ----------- = 5 1/2
     x                          2y                  2y                  2

BigorU [14]

Answer:

1486.67 or 1487.

Find the average of those three things. Add 2,340 plus 470 plus 1650. You get 4460. Since you have three costs, divided 4460 by 3, which is 1486.6 repeating. Round to the nearest hundredth which is 1486.67. Hope this helps!
