How do I write a formula that will add all the sales for an individual,
return the name in one cell and the total sales in another and list them by
highest dollar sold descending?

Example of what I will enter into Excel:

Jim $100.00
Jim $126.78
Jim $153.56
Rose $180.34
Rose $207.12
Rose $233.90
Rose $260.68
Rose $287.46
Bill $314.24
Bill $341.02
Bill $367.80
Bill $394.58
Bob $421.36
Bob $448.14
Bob $474.92
Bob $501.70
Bob $528.48
Bob $555.26

This is what I would like the results to look like:

Bob $2,929.86
Bill $1,417.64
Rose $1,169.50
Jim $380.34


Thanks for your help.
