Find the correct value of the items

Answer to Problem 1.2.9P
Explanation of Solution
Given information:
Kelly buys 3 video games that cost 18.95 each
Kelly buys 2 pair or earbuds that cost 11.50 each
Kelly has a coupon for 2 off the price of each video game
Kelly uses the calculater then total cost of the items is 77.85 and The cashier tells her that the total cost is 73.85
1 Video game cost = 18.95
then 3 Video game cost =
3 Video game cost = 56.85
Each video game discount = 2
then 3 Video game discount =
3 Video game discount = 6
Final Price of the Video game =3 Video game cost - 3 Video game discount
Final Price of the Video game =
Final Price of the Video game =
1 Earbuds cost = 11.50
Then 2 Earbuds cost =
2 Earbuds cost =
Total Cost of the Items = Final price of the video game + 2 Earbuds cost
Total Cost of the Items =
Total Cost of the Items =
Conclusion-
Chashier total cost is right
