Identify the percent of change as an increase or a decrease. 50 pounds to 35 pounds. Find the percent of change.
Solnce55 [7]
Since it starts at 50 and goes to 35....it is a decrease since the amount is going down, or getting smaller.  To find the percent, first find the difference 50-35 = 15; then divide by the initial amount of 50.  So, 15/50 = 0.3, and then convert that to a percent by multiplying by 100.  Therefore the percent decrease is 30%
