Help needed w/ "Table 1 shows the cost of producing each pound of raw cotton goods"

Do you understand what "percentage change" means? To get the actual "amount" of change, subtract the previous amount from the latter amount. For example, if some quantity changed from 20 to 25 the actual amount of change is 25- 20= 5. Going from 20 to 25 the amount has increased by 5. The "percentage change" is that change divided by the initial amount, 5/20= 1/4= 0.25. The change is 1/4 or 25% of the initial amount. Do that with the numbers you are given.
