In September, John sold \(\frac{2}{3}\) more soap than in February. In November, he sold 5 percent more than in September. John's November sales were what percent greater than his February sales?

(A) \(\frac{10}{3}\)%

(B) 65%

(C) \(\frac{214}{3}\)%

(D) 75%

(E)\(\frac{514}{3}\)%

\(s=(1 + \frac{2}{3}).f = \frac{5}{3}.f\) and then \(f = \frac{3}{5}.s\)

But, \(n = (1 + 0,05).s = 1,05.s\)

Thus, \(\frac{n}{f} = \frac{1,05.s}{0.6s}=\frac{1.05}{0.6}=1.75\).

John's November sales is 75% percent greater than his February sales.

The correct answer is letter

(D).
