The student locker numbers at Olympic High are numbered consecutively beginning with locker number 1 1. The plastic digits used to number the lockers cost two cents apiece. Thus, it costs two cents to label locker number 9 9 and four centers to label locker number 10 10. If it costs $137.94 \$137.94 to label all the lockers, how many lockers are there at the school? <spanclass=′latex−bold′>(A)</span> 2001<spanclass=′latex−bold′>(B)</span> 2010<spanclass=′latex−bold′>(C)</span> 2100<spanclass=′latex−bold′>(D)</span> 2726<spanclass=′latex−bold′>(E)</span> 6897 <span class='latex-bold'>(A)</span>\ 2001 \qquad <span class='latex-bold'>(B)</span>\ 2010 \qquad <span class='latex-bold'>(C)</span>\ 2100 \qquad <span class='latex-bold'>(D)</span>\ 2726 \qquad <span class='latex-bold'>(E)</span>\ 6897
