We reached our goal by 2000 customers this month which is 14% more than last month." employee: "that means that we must have customers last month."

1754.39 helped last month

Explanation:

Let's just get the answer. Then we can comment.

Let last month = x

x + 14% * x = 2000                If we take 14% of last month and add it to last month, we should be able to get 2000.

x + (14/100)x = 2000             14/100 = 0.14

x + 0.14x = 2000                   Add 0.14x and x

1.14 x = 2000                         Divide by 1.14

1.14x / 1.14 = 2000/1.14

x = 1754.39                            Last month's help number was 1754.39

Is this correct?

0.14 * 1754 = 245.61

If you add this to 1754.39, you should get 2000

1754.39

245.61

2000.00 which is exactly what we should get.
