12.Hi, I have one question on my math homework that I can't seem to figure out. Please help me! Here ...

is Imagine that in the voting for a certain award, 7 points are awarded for first place, 4 points for second, 3 points for third, 2 points for fourth, and 1 point for fifth. Suppose there were five candidates (A, B, C, D, and E) and 47 voters. When the points were tallied, A had 155 points, B had 173 points, C had 170 points, and D had 154 points. Find how many points E had and give the ranking of the candidates. (Hint: Each of the 47 ballots hands out a fixed number of points. Figure out how many, and take it from there.)
