Maths problem

Can anybody help me solve this maths problem?

Thirty seeds have been planted. After one week, some of them are 5cm high, a SMALLER number are 2cm high, and the rest are 1cm high. After another week, every plant had doubled size EXCEPT for one, which was 1cm high. The total height of all of these plants came up to 131cm.

How many plants of each height were there after ONE week? Thanks :)
