0.4(2x+0.5)=3[0.2x+(-2)]-4

0.8x+0.2=0.6x-6-4 

0.8x-0.6x=-6-4-0.2

0.2x=-10.2 

x=-10.2/0.2

x=-51

$0.4(2x+0.5)=3[0.2x+(-2)]-4$ 

 $0.8x+0.2=0.6x-10$

$0.2x=-10.2$

$x= \frac{-10.2}{0.2}$

$x=-51$

WARRIOR [948]

Answer:

$386.75

Step-by-step explanation:

First we must find the price of the camera after the man sold it, with the 10% loss.

To do this we find 10% of 414, which is 41.4 . Meaning the camera was originally bought from the dealer for $455.40, as we have to add the 10% back onto the price.

Now we find 15% of 455 and subtract it, with 15% being 68.25, the original cost was $386.75. My guy was seriously ripped off :(.
