mark just bought a new vacuum cleaner for $220. he used a 30% off coupon and then paid 5.1% sales tax. what was his final cost?

Answer: $161.85

Step-by-step explanation: $220 is the original price. you want to first deduct the 30% tax. Find out the 30% tax by multiplying 220 x. 30 = 66. So deduct the $66 from $220 to get $154. That is the price. You will need to add on the 5.1% tax. So to get the tax you multiply $154 by. 051 to get $7.854. Add that to the $154 sales price to get a total of $161.854. But since money, you can't have a portion of a cent so you round the 4 down
