1000 wooden logs were used
Solution:
Given that There is a wood shop that makes boats
The number of boats constructed can be determined by the equation:
B = 0.04w
Where "B" is the number of boats
"w" is the number of wooden logs used
To find: number of wooden logs used when 40 boats are used
To find the number of wooden logs used, substitute B = 40 in given equation
B = 0.04w
40 = 0.04w

Thus 1000 wooden logs were used
