What is 0.5-0.2x=0.3(x+3) ?

1 answer:

6 0

0.3(x + 3 ) = 0.3x + 0.9 ;
We solve the equation 0.5 - 0.2x = 0.3x + 0.9 / - 0.3x;
0.5 -0.2x = 0.9 / -0.5;
-0.2x = 0.4 / × 10 ;
-2x = 4 / ÷ ( - 2 );
x = -2 ;
The solution of the equation is -2 .

PilotLPTM [1.2K]

Answer:

$825.60

Step-by-step explanation:

Since the price of it is $960.00, it means that it's 100%.

100% = 960

1% = 960 ÷ 100 = 9.6

14% = 9.6 x 14 = 134.40

Since they asked for after the discount, deduct the price of the discount with the original price.

Mountain bike after 14% discount =

960 - 134.40 = 825.60
