    Only 1/16 cause it is (1/2)^4.

    C because the first kid would have 1/2 the second kid would have 1/4 the third kid would have 1/8 and the forth kid would have 1/16

    If n and ok are postive integers and eight^n=2^ok, what's the cost of n/ok? 8^n = 2^3n =2^ok so 3n =ok so n/ok = a million/3 you have not indicated what the sale cost is, so difficulty won't be able to be responded. in case you mean f(x)= 3x+4, then 2f(x) = 6x+8 G/P = 5/3 ---> G = 5P/3 P + G = 120,000 P +5P/3 =120,000 8P/3 =120,000 P = 3*120,000/8 = 40 5,000 in user-friendly words a million or 2 satisfies the inequality. therefore the opportunities are 2/10 or a million/5
