Sure. Create a sum list called SCORES. Put 75, 89, and 66 in it. Then enter this solver equation and solve for A:

A=SIGMA(I:1:SIZES(SCORES):1:ITEM(SCORES:I))

You should get 230. I think both the 17b and 19b would do this fine.

Of course, use the sigma symbol for SIGMA, I'm just too lazy to look up the Latex code.
