Question

John just hired a new employee to work in your bakeshop. In one hour the employee burned 150 chocolate chip cookies. If this represented 15% of the days production, how many cookies did you plan on producing that day?

Answer 1

If 150 chocolate chip cookies are 15% of the days production, then we may write it down as:

150 = 15% from x
150 = 15/100x
150 = 3/20x                        / * 20 (both sides)
3000 = 3x                          / ÷ 3 (both sides)
x = 1000

Answer: I planned producing 1000 cokies that day.
