58.1 lb

Work Step by Step

To find the part that is lost, multiply the base weight times the shrinkage rate. Move the decimal two places to the left to convert the percentage to a decimal. $P=BR=70\ lb\times17\%=70\ lb\times0.17=11.9\ lb$ Deduct the shrinkage from the original weight to find the remaining part. $70\ lb-11.9\ lb=58.1\ lb$
