Answer 3

The TV costs 600 and the mount costs 29.99 as stated by the problem.

Part A) she purchases both the TV and the mount so you can simply add 600 + 29.99 to get 629.99. However, she has a 30% off coupon so calculate 30 % of the total or simply 0.3*629.99. Finally, subtract the discount from the original price to get the amount she actually paid.

Part B) from the amount paid in part A), she will pay a 7% sales tax, so calculate 7 % of the total and add it onto the total to get the amount paid after tax.

Part C) she will tip 10% of the *original* price (629.99 as determined in part A), so calculate 10 % of 629.99 and add this to the after-tax total from part B.
