To solve the problem, we need to use the formula for percent increase:

percent increase = (new value - old value) / old value * 100%

Let X be the number of ice cream cones sold 5 years ago. We can set up the following equation:

40% = (25,000 - X) / X * 100%

Simplifying and solving for X, we get:

X = 17,857.14

Rounding to the nearest integer, we get:

X ≈ 17,857

Therefore, the answer is choice B: 17,857 ice cream cones. Let's call the number of ice cream cones sold 5 years ago "x".

We know that sales went up 40%, which means that the current year's sales are 140% of the sales from 5 years ago.

We can set up an equation:

140% of x = 25,000

To solve for x, we need to divide both sides by 1.4:

x = 25,000 ÷ 1.4

x ≈ 17,857

Therefore, the answer is B.
