If a pair of jeans normally sells for $35 and is on sale for 20% off, the sale price can be calculated as follows:
Sale price = $35 - 20% of $35
Sale price = $35 - $7
Sale price = $28
Therefore, the sale price of the jeans is $28.
To find the total cost of the jeans including sales tax at a rate of 6%, we need to add the sales tax to the sale price. The sales tax is calculated as 6% of the sale price:
Sales tax = 6% of $28
Sales tax = $1.68
So, the total cost of the jeans is:
Total cost = sale price + sales tax
Total cost = $28 + $1.68
Total cost = $29.68
Therefore, the total cost of the jeans with sales tax included is $29.68.
