The problem is- the original cost for a pair of boots was $85.65 but you have a coupon for 30% off. What will you owe the cashier?

First make 30% into a decimal by moving the decimal over two places to the left. That will make it .30.

Now you take $85.65 times .30

Now you take $85.65 times .30

That equals $25.6950

That equals $25.6950

But you need to round it up. So you take away the zero and the 5 rounds up to 10 from the 9 so you just add one more to the 6.

Now you take $85.65 minus $25.70.

Now you take $85.65 minus $25.70.

That equals $59.95.

That equals $59.95.

So you will hand the cashier $59.95.
