So you have to multiply the 2 and the n first and the 2 and the 5.
So that's 2n+10. Next, you have to subtract 10 from both sides and cross the previous 10 out (because they cancel out). Then, you bring down the 2n and the -12.

(2n-12) Last you divide everything by 2 and you get:

n=-6!

TA-DA!!!

Indigo Depot is having a clearance sale of their fall items. A jacket that originally cost $120 before any discount is on sale f

Sauron [17]

Answer:

The final price is $66.

Step-by-step explanation:

This question can be solved by a rule of three.

The initial price was of $120.

Initially, there was a discount of 15%. Then, there is another discount on the initial price. So the total discount is of 15+30 = 45%.

So the final price will be 100-45 = 55% = 0.55 of the initial price.

$120 - 1

x - 0.55

$x = 0.55*120 = 66$

The final price is $66.
