Hi Sandy,

I'd be happy to help you with this pricing strategy challenge in Excel!

To round up or down to the nearest $.09, you can use the MROUND function in Excel. Here's how:

1. First, enter the original price of the item in a cell. Let's say the price is $5.73 and the cell is A1.
2. In another cell, enter the formula "=MROUND(A1,0.09)". This formula will round the price in cell A1 to the nearest $.09.
3. The result will be $5.76, which is the rounded price.

To break down the formula a bit more, the MROUND function takes two arguments: the number you want to round, and the multiple to which you want to round. In this case, we want to round to the nearest $.09, so we use 0.09 as the second argument.

You can also use this formula to round a range of prices at once. For example, if you have a list of prices in cells A1:A10, you can enter the formula "=MROUND(A1:A10,0.09)" in cell B1 to round all the prices to the nearest $.09.

I hope this helps you automate your pricing strategy and save some time!
