The original price of a pair of shoes is $42. The sale price 20% off the orginal price. Sales tax of 7% is added to the sale price. What is the final cost of the pair of shoes? Roundto the nearest cent​

Answer:

$35.95

Step-by-step explanation:

Since 20% is taken off, that means the sale price is 80% of the original price

42 x . 8 = 33.6

Now, we have to add the sales tax to the new price, 7%

33.6 x 1.07 = 35.952

Another-but longer-way to add sales tax is this:

33.6 x .07 = 2.352

2.352 + 33.6 = 35.952
