David just hired a new employee to work in your bake shop in one hour the employee burned 55 chocolate chip cookie if this represented 15% of the day production how many cookie did you plan on producing that day?

To find out how many cookies were planned to be produced that day, we can set up a proportion based on the given information.

Let's denote the planned number of cookies as "x".

We have the following information:
- The employee burned 55 chocolate chip cookies, which represents 15% of the planned production.

We can set up the proportion as follows:
(55 / x) = (15 / 100)

To solve for "x", we can cross-multiply and solve for it:
55 * 100 = 15 * x

5500 = 15x

Now, divide both sides of the equation by 15:
5500 / 15 = x

x = 366.67

Since you can't produce a fraction of a cookie, we'll round up to the nearest whole number. Thus, the planned number of cookies for that day is 367.
