Danny just hired a new employee to work in your bakeshop. In one hour the employee burned 625 chocolate chip cookies. If this represented 25% of the day’s production, how many cookies did you plan on producing that day?

2500

Explanation:

You know that the new employee burned 625 chocolate chips in one hour and that this many chocolate chips represented 25% of that day's production.

As you know, percentages are used to express fractions that have 100 as their denominator. In this case, you can say that

25% = 25/100

This means that for every 100 chocolate chips baked that day, 25 were burned by the new employee. You can simplify this ratio to get

25/100 = 1/4 -> one chip burned for every four chips baked

Since you know how many chocolate chips were burned, you an scale up this number by using the 1/4 ratio to find the total number of chocolate chips baked

625 color(red)(cancel(color(black)("burned"))) * "4 baked"/(1color(red)(cancel(color(black)("burned")))) = "2500 baked"

Therefore, the bakeshop baked 2500 chocolate chips that day.
