The FAA now figures the average checked bag to weigh 19 pounds. This is up from a previous figure of 12 pounds. Find the amount of increase and the percent of increase, to the nearest whole percent.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
