Question

Rex weighed 80 pounds a year ago. Now he weighs 92 pounds. What is the percent increase in his weight?

Answer 1

So base on the question, that states the weight of Rex from last year to the present, and find its rate if change or percentage of change. To calculate the percentage you must first subtract the said weight in the present to its past then divide it by its past weight then multiply it by 100. So the percentage would be 15 %. I hope this would help
