Step-by-step explanation:

Let's start by analyzing the information we have.

First we know that the regular price of the vests is $ 15.99.

But now they are on sale, so they cost $ 13.99. But at the time of paying them, they tell us that a 5% tax will be applied.

So we must add that 5% to the amount we will pay. And we will do this by multiplying that amount by 5, and dividing it by 100:

5. 13.99 = 69.95: 100 = 0.6995

Now we will add the price of the tax to the value of the vests:

13.99 + 0.6995 = 14.6895

If before they cost 15.99 we just have to do the subtraction:

15.99 - 14.6895 = 1.3005

In this way we can verify that we will save $ 1.30 buying on sale.
