Answer:
12.5%
Step-by-step explanation:

= 12.5%
Percentage of total cost that is the payments= 12.5%
2/5 is equivalent to 4/10 so at the end of February 4/10 was used up
And at the end of January, 3/10 was used
so 4/10 + 3/10 = 7/10
At the end of February, 7/10 of the wood was used
A+7=0
A+7-7=0-7
A=-7
B+3=7
B+3-3=7-3
B=4
