3. The regular price of boots at shoe carnival are $ 104. The boot are on Clearance for 30% off and then a customer uses a 20% off coupon after that. What is the final cost of the boots?

Hey there!

The answer to your question is $58.24

First, we will find the clearance price by finding 70% of the original price, since 30% was taken off:

0.70 x 104

72.80

Then, we will find the price after the coupon by finding 80% off 72.80, since 20% was taken off:

0.80 x 72.80

58.24

Hope it helps! Have a great day!

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.
