The formula for the number of combinations of choosing "r" objects from a larger set of "n" is
combinations = n! / r! * (n - r)!
we know combinations = 35 and r = 3 so we have to solve for "n"
35 = n! / 3! * (n -3)!
n = 7 colors were available
A. 3x+4y+2=0 ----------linear
B. X= 2,4,6,8 Y=1,5,15,30 -------nonlinear
