A store is having a closing sale. All items in the store are 35% off. Samantha found a jacket she wants to buy with an original price tag of 85$. Wich expression will find the price of the jacket after applying the sale?

The final price paid by Samantha is 55.25 $

Step-by-step explanation:

In order to find out the final price of the jacket for Samantha we need to calculate how much 35% of 85 $ is and subtract the original price by it. So we have:

price of discount = 85*(35%) = 85*(35/100) = 85*(0.35) = 29.75 $

Now we can compute the final price by subtracting the original price by the price of discount. So we have:

final price = original price - price of discount = 85 - 29.75 = 55.25 $

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
