Mabel lives 4500 steps directly east of Lake High school. Helen lives 3/4 the number of steps that Mabel lives, directly west of the school. What's the total number of steps Mabel will walk to visit Helen so that they can do their assignments together?
Thoughts? Step-by-step reasoning:
Helen lives 3 / 4 * 4500 = 3375 steps directly west of Lake High. To reach Helen, Mabel would have to walk to 4500 + 3375 = 7875 steps.
Thus, the answer is 7875.
