With a 30% off coupon for jeans priced at $78.95, how much will Dave pay after including taxes?

To determine how much Dave will pay for the jeans after applying the 30% discount and including taxes, it's essential to follow the steps of calculating the discount, the taxable amount, and then the final total.

Initially, the price of the jeans is $78.95. A 30% discount means that we can calculate the amount of the discount by multiplying the price by 0.30:

Discount = $78.95 × 0.30 = $23.685

Next, we subtract the discount from the original price to find the new price:

New Price = $78.95 - $23.685 = $55.265

Now, assuming a sales tax rate, for example, of 6%, we need to calculate the amount of taxes on the new price. First, let’s round the new price to a suitable figure for easier calculation (this could lead to a small difference based on how taxes would be calculated in practice):

Tax = $55.265 × 0.06 = $3.316

Now we add the tax back to the new price to find out the total amount Dave will pay:

Total Price = $55.265 + $3.316 = $58.581

When rounded appropriately
