The largest whole number such that seven times the number is less than 100 is

$\text{(A)} \ 12 \qquad \text{(B)} \ 13 \qquad \text{(C)} \ 14 \qquad \text{(D)} \ 15 \qquad \text{(E)} \ 16$

We want to find the smallest integer $x$ so that $7x < 100$ . Dividing by 7 gets $x < 14\dfrac{2}{7}$ , so the answer is 14. $\boxed{(C)}$
