35 = 70%
If you divide 35 by 7, you will find what 10% of your maximum bid is.
35/7 = 5
5 = 10%
Multiply your value of 10% by 10 to get 100%.
5*10 = 50
Your maximum bid would be $50. You actually spend $35. To find the amount more you were willing to pay, subtract the two values.
$50-$35 = $15
Answer: You were willing to pay 15 more dollars than you did.
The answer to your question would be 6!
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
