Saw A = 150 planks/30 seconds = 5 planks per second
Saw B = 130 planks/ 13 seconds = 10 planks per seconds

Answer:
Cost of the item sold= $1,223
Step-by-step explanation:
Let
x= cost of the item sold
$97.84=commission on the item
Percentage of the commission=8%
To find the cost of the item sold
Commission=8% of cost of the item
97.84=0.08 * x
97.84=0.08x
Divide both sides by 0.08
97.84 / 0.08 = 0.08x / 0.08
1,223=x
x=$1,223
Therefore, cost of the item sold= $1,223
