In Excel, which equation would be of the correct form if a
static reference were to be made to the cells B1 (Acc) and B2 (V_initial)
with C1:C10 (time) and D1:D10 being V_final? based off of V_final = V_initial + Acc * time

A. $B$2 + $B$1 * C10
B. B2 + B1 * C10
C. B2 + B1 * $C$1
D. none of the above

thanks for the help!
