Alberts hair was 5 centimeters long after his last haircut and it grows 4 cm every year. how many years will it take until alberts hair is 33 cm long

Here's how I did this problem.

Alberts hair is already 5 centimetres long. We know that his hair grows by 4 centimetres every year, and we have to figure out how long it takes until his hair is 33 centimetres. So, it's easier to subtract 33 from 5, and see if that result is divisible by 4, and it is, because 33-5 is 28, which goes into 4, 7 times. (4*7 = 28), so it will take Albert 7 years, until his hair is 33 centimetres long.

Hope this helped.

The answer is 7. The answer is 7 because 33-5=28, and 28/4=7, so the answer is that it will take 7 years for his hair to grow to 33 centimeters.
